Fig. 1 shows the flow diagram of image processing method according to an embodiment of the invention.As shown in Figure 1, should Method includes the following steps：

Step S110, multiple key points corresponding to process object in detection image, according to multiple key points determine with Deal with objects corresponding pending area.

Wherein, image can be video camera shooting photo, can also be shooting video flowing in picture frame, processing pair As that can be facial area in image, face etc., this is not limited by the present invention.For the process object in image, inspection The multiple key points for surveying process object in practical application, can fix the process object in image in advance, i.e., only needle in processing procedure Fixed multiple process objects are handled or process object that user also can voluntarily in selected digital image, the present invention is to this It is not construed as limiting.

In the application scenarios handled facial image, process object can be face or face position, then close Key point can be characteristic point corresponding with facial face and/or face contour, and it is right can specifically to refer to institute on face contour position Characteristic point corresponding on corresponding characteristic point and the other positions of face in the characteristic point answered, facial face position.It needs Illustrate, the present invention is not construed as limiting the mode for detecting key point.

Multiple key points corresponding to the process object detected determine corresponding with process object in image wait for Processing region, region shape, region contour and regional extent of pending area etc. can be according to each passes of process object Key point is determined.Such as, however, it is determined that it deals with objects as the eyes in image, then according to the more of the eyes detected A key point determines pending area corresponding with eyes.

Step S120 judges whether the pixel belongs to pending area for each pixel in image, if so, Then follow the steps S130；If it is not, this method terminates.

It is determined that pending area corresponding with process object, the pixel in pending area are according to step S120 It is the pixel handled, in concrete application, coordinate system can be established in the picture, calculates each pixel in image and exist Coordinate value in the coordinate system judges whether the pixel belongs to pending area according to the coordinate value of pixel, or according to The distance between the center of pixel and pending area judges whether the pixel belongs to pending area.This method is to judging Whether pixel belongs to the mode of pending area without limiting, and those skilled in the art can set according to actual needs It sets.

Step S130 is determined and the pixel phase according to the distance between the pixel and the regional center of pending area The pixel is moved to target location by corresponding translation distance information according to translation distance information.

In practical application, micro-shaping special effect processing is carried out to image and often only needs to handle the partial pixel point in image, Without traversing pixel all in image, the pixel handled is determined with specific reference to obtained pending area is divided Point, therefore, if judging in this step, the pixel belongs to pending area, according to the area of the pixel and pending area The distance between domain center carries out translation processing to the pixel.

Wherein, the regional center of pending area can be according to the region shape of pending area, regional extent and detection To process object corresponding to multiple key points be determined, for example, multiple key points corresponding to eyes are true The region shape for determining pending area is ellipse, and the center key point of eyes is determined as the ellipse pending area Regional center.

The distance between regional center of pixel and pending area can be calculated according to the coordinate value of the pixel, Specifically, image coordinate system is established in the picture, calculates separately the coordinate value of the pixel and area under the image coordinate system The coordinate value at domain center is further calculated according to pixel and the coordinate value of regional center between pixel and regional center Distance.

According to pixel and the determining translation distance information corresponding with the pixel of the distance between regional center, specifically Can be according to the mapping relations between the distance between pixel and regional center and translation distance information, determination is opposite with pixel The translation distance information answered, translation distance information may include：Translation distance, translation direction.Further believed according to translation distance The pixel is moved to target location by breath, can specifically determine that target is sat according to the coordinate value of translation distance information and pixel Scale value determines the corresponding target location of coordinates of targets value, the pixel value of the pixel is assigned to positioned at the mesh in the picture Pixel at cursor position, this completes carry out translation processing to pixel.

The image processing method provided according to the present embodiment, multiple keys corresponding to process object in detection image Point determines pending area corresponding with process object according to multiple key points；For each pixel in image, judge Whether the pixel belongs to pending area；According to the distance between regional center of the pixel and pending area determine with The pixel is moved to target location by the corresponding translation distance information of the pixel according to translation distance information.Thus may be used Know, which is carried out only for the pixel in pending area at translation without handling all pixels point in image Reason, can reduce operand, promote the speed of image procossing, and can reach and be translated to the process object in image Effect.

Fig. 2 shows the flow diagrams of image processing method in accordance with another embodiment of the present invention, wherein this implementation The method of example can realize that, it is, of course, also possible to realize by other means, this is not limited by the present invention by graphics processor. As shown in Fig. 2, this approach includes the following steps：

Step S210, multiple key points corresponding to process object in detection image, according to multiple key points determine with Deal with objects corresponding pending area, wherein pending area is oval pending area, and oval pending district Domain is determined by the oval center of circle, oval horizontal axis and the oval longitudinal axis.

Wherein, image can be video camera shooting photo, can also be shooting video flowing in picture frame, the present invention This is not construed as limiting.For the process object in image, multiple key points of detection process object, in practical application, system can Process object in preselect image, i.e., only for it is fixed some handled, also can be according to actual needs The voluntarily process object in selected digital image, you can according to the quantity and type of user demand adjustment process object, the present invention is to this It is not construed as limiting.

In the application scenarios handled facial image, process object includes：Facial area, face contour and/or Face position；Wherein, face position includes at least one of the following：Eyes, nose, eyebrow, face and ear, then locate Multiple key points corresponding to reason object include facial area, the corresponding characteristic point of face contour and/or face position, specifically Corresponding characteristic point and the other portions of face in characteristic point, facial face position corresponding to can referring on face contour position Corresponding characteristic point on position.In addition, number, distributing position and the detection of the present invention key point corresponding to process object Mode is not restricted, and every mode that can detect key point should be all included within the scope of the present invention.

In existing micro-shaping special effect processing technology, generally require to handle all pixels point in image, for figure Each pixel as in is handled, and micro-shaping special effect processing technology is at subregion in image Reason, for example, carrying out micro-shaping special effect processing for an image comprising face, it is thus only necessary to the pixel in human face region It is handled, the pixel outside human face region need not then carry out handling or only doing the adjustment of adaptability, therefore, in order to reduce Operand improves the speed of graphics process, and the method for the present embodiment determines pending area according to the key point of process object, only Translation processing is carried out for the pixel in pending area.

In a kind of application scenarios handled facial image, pending area is oval pending area, then The oval center of circle, oval horizontal axis and the oval longitudinal axis are determined according to the key point of process object, further according to the oval center of circle, ellipse Horizontal axis and the oval longitudinal axis determine the ellipse processing region.Since the profile of face and face position is similar to ellipse Shape, setting pending area to oval processing region can make pending area more be bonded face or face position Profile, and can make in pending area to include the pixel that need not be handled as few as possible, to reduce operation Amount, promotes the speed of processing.Wherein, oval horizontal axis is orthogonal with the oval longitudinal axis, but the present invention to oval horizontal axis with And the specific orientation of the oval longitudinal axis is not construed as limiting, those skilled in the art can be adjusted according to actual needs.

It should be noted that oval pending area in the present embodiment and not merely refer to the length of oval horizontal axis with it is ellipse The unequal oval pending area of length of the circle longitudinal axis, since circle is also a kind of special ellipse, ellipse Pending area can also refer to the round pending area of the length and the equal length of the oval longitudinal axis of oval horizontal axis, specific to need Determines according to actual conditions.

Optionally, pending area further comprises：Target treatment and environmental treatment region；Then according to multiple passes Key point is determined to be specifically included with the step of dealing with objects corresponding pending area：

According to the profile and/or shape of process object, determine at the target corresponding with process object for including in image Manage region；According to target treatment, determine positioned at the environmental treatment region of target treatment periphery.

In practical application, the pixel in some region in image is handled and to the pixel except the region In the case that point keeps reset condition, the image that may result in after treatment seems unnatural, and variation trace is apparent, therefore It is also required to do corresponding processing to the partial pixel point except the region.

Pending area is further divided into target treatment and environmental treatment region by the method for the present embodiment, by In target treatment determined according to the profile and/or shape of process object, therefore, target treatment is to fit well on place The region for managing object, will be determined as environmental treatment region positioned at the subregion of target treatment periphery, then is directed at target Pixel in reason region and the pixel in environmental treatment region can take different processing rules to be handled, and be cut with this Weak variation trace.For generically, environmental treatment region can be interpreted as to a buffer area, in target treatment Pixel needs to carry out the relatively large processing of change degree, and then can only be fitted to the pixel in environmental treatment region The adjustment of answering property.

Optionally, target treatment is elliptical object processing region, and environmental treatment region is positioned at elliptical object The oval ring-type environmental treatment region of processing region periphery.It follows that pending area includes elliptical object processing region With oval ring-type environmental treatment region.

Then according to the profile of process object and/or shape, the target corresponding with process object for including in image is determined The step of target area shape and target area range of processing region, specifically includes：

The target center of circle is determined according to multiple key points and passes through the target horizontal axis and/or the target longitudinal axis in the target center of circle, root The target of elliptical object processing region is determined according to the target center of circle and by the target horizontal axis and/or the target longitudinal axis in the target center of circle Region shape and target area range；

According to the target area shape and target area range of target treatment, determines and be located at outside target treatment The step of environmental area shape and environmental area range in the environmental treatment region enclosed, specifically includes：

The target center of circle is determined as the oval center of circle, oval horizontal axis and/or ellipse is determined according to target horizontal axis and/or the target longitudinal axis The circle longitudinal axis determines oval pending area according to the oval center of circle, oval horizontal axis and the oval longitudinal axis；It is pending according to ellipse Region and elliptical object processing region are determined positioned at the oval ring-type environmental treatment area of elliptical object processing region periphery Domain.Wherein, the length of oval horizontal axis is the first preset multiple of the length of target horizontal axis, and/or the length of the oval longitudinal axis is mesh Mark the second preset multiple of the length of the longitudinal axis；Wherein, the first preset multiple and/or the second preset multiple are not less than 1.

The target center of circle is determined according to multiple key points with process object, it specifically can be by the corresponding center of process object Key point is determined as the target center of circle, then, according to the position relationship and distance between the target center of circle and each key point, determines The locality and length of target horizontal axis and the locality and length of the target longitudinal axis, further according to the target center of circle, target Horizontal axis and the target longitudinal axis determine the regional extent of target treatment.For example, when process object is eyes, it is determined that Eye center key point is the target center of circle, determines the canthus key point for connecting eye center key point to the eyes either side Line segment be target horizontal axis, determine connection eye center key point and the upside of the eyes or the line segment of downside boundary key point For the target longitudinal axis.Finally, elliptical object processing region is determined according to the center of circle, target horizontal axis and the target longitudinal axis.

Then, oval pending area, as shown in the above, ellipse are determined according to elliptical object processing region Target treatment is concentration ellipse shape region with oval pending area, can specifically make target horizontal axis and oval horizontal axis phase Overlap and the target longitudinal axis coincide with the ellipse longitudinal axis, and set the length of oval horizontal axis to target horizontal axis length the One preset multiple, and the oval longitudinal axis length be set as the target longitudinal axis length the second preset multiple, wherein first is default Multiple can be identical with the second preset multiple, then in the case, target horizontal axis and the transverse and longitudinal ratio and ellipse of the target longitudinal axis are horizontal Axis is equal with the oval transverse and longitudinal ratio of the longitudinal axis, and the first preset multiple can also be different with the second preset multiple, but the numerical value of the two In at least one cannot be less than 1, that is, the regional extent of oval pending area is more than the region model of target treatment It encloses.It is further determined according to oval pending area and elliptical object processing region and is located at elliptical object processing region The oval ring-type environmental treatment region of periphery, that is to say, that elliptical annular environmental area is to be located at elliptical object treatment region Oval ring region between domain and oval pending area.

Step S220 determines the original abscissa value of the pixel and original vertical for each pixel in image Coordinate value.

In concrete application, coordinate system can be established in the picture, for each pixel in image, calculate pixel at this Original abscissa value under coordinate system and initial ordinate value specifically establish region in the picture according to pending area Coordinate system calculates original abscissa value and original of the pixel under the Regional coordinate system for each pixel in image Beginning coordinate value.Optionally, when pending area is oval pending area, the oval center of circle is determined as coordinate system in advance Coordinate origin determines the transverse coordinate axis of coordinate system according to oval horizontal axis, and the longitudinal coordinate of coordinate system is determined according to the oval longitudinal axis Axis calculates the original abscissa value and initial ordinate value of the pixel according to coordinate system.That is, the above-mentioned target center of circle is made For coordinate origin, the transverse coordinate axis of coordinate system is determined according to target horizontal axis, determines that the longitudinal of coordinate system sits according to the target longitudinal axis Parameter calculates the original abscissa value and initial ordinate value of the pixel according to coordinate system.

Step S230, according to the transverse and longitudinal ratio between the length of oval horizontal axis and the length of the oval longitudinal axis to the pixel Original abscissa value obtains the scaling abscissa value of the pixel after zooming in and out processing.

The method of the present embodiment by calculate pixel to ellipse the center of circle between equivalent circumferential distance, further according to etc. Effect circumferential distance judges whether the pixel belongs to the ellipse pending area.Specifically, the length of oval horizontal axis is calculated first The transverse and longitudinal ratio of degree and the length of the oval longitudinal axis, place is zoomed in and out using the transverse and longitudinal ratio to the original abscissa value of the pixel Ratio between original abscissa value and transverse and longitudinal ratio, is determined as the scaling abscissa value of the pixel by reason.Wherein, first In the case that preset multiple is equal with the second preset multiple, scaling transverse and longitudinal coordinate value also can be according to the length and target of target horizontal axis The transverse and longitudinal ratio of the length of the longitudinal axis and the original abscissa value of pixel are determined, similar with aforesaid way, no longer superfluous herein It states.

In addition, when the length of oval horizontal axis and the equal length of the oval longitudinal axis, i.e., pending area is round pending Region, the transverse and longitudinal ratio between the length of oval horizontal axis and the length of the oval longitudinal axis are 1.

Step S240 calculates the pixel and ellipse using the initial ordinate value and scaling abscissa value of the pixel Equivalent circumferential distance between the center of circle.

The method of the present embodiment, can be oval horizontal by calculating the equivalent circumferential distance between pixel and the oval center of circle The oval pending area that the length of axis is different from the length of the oval longitudinal axis is equivalent to round pending area, for each picture Vegetarian refreshments, judges whether the pixel belongs to pending area.In practical applications, the equivalent circular between pixel and the oval center of circle All distances can be calculated by the following formula:

D=[(x/ratio)²+y²]^1/2

Wherein, D is the equivalent circumferential distance between pixel and the oval center of circle, and x is the original abscissa value of pixel, y For the original coordinates value of pixel, ratio is the transverse and longitudinal ratio between the length of oval horizontal axis and the length of the oval longitudinal axis, then x/ Ratio is the scaling abscissa value of the pixel.

Step S250, judges whether the equivalent circumferential distance between the pixel and the oval center of circle is more than the length of the oval longitudinal axis Degree, if it is not, thening follow the steps S260；If so, this method terminates.

Judge whether the equivalent circumferential distance between pixel and the oval center of circle is more than the length of the oval longitudinal axis, which is It is to judge whether the pixel belongs to pending area.It should be noted that object of the equivalent circumferential distance compared with have pair It should be related to.Specifically, if equivalent circumferential distance is according to the transverse and longitudinal ratio between the length of oval horizontal axis and the length of the oval longitudinal axis Value zooms in and out the scaling abscissa value of the pixel obtained after processing and original to the original abscissa value of the pixel What ordinate value was calculated, then it is ellipse to judge whether the equivalent circumferential distance between the pixel and the oval center of circle is more than for this step The length of the circle longitudinal axis；If equivalent circumferential distance is the aspect ratio between length and the length of oval horizontal axis according to the oval longitudinal axis The scaling ordinate value of the pixel obtained after processing and original cross are zoomed in and out to the initial ordinate value of the pixel What coordinate value was calculated, then this step judges whether the equivalent circumferential distance between the pixel and the oval center of circle is more than ellipse The length of horizontal axis, those skilled in the art can be adjusted according to actual conditions.In other words, in the present embodiment horizontally and vertically It can be interchanged, correspondingly, transverse and longitudinal ratio is changed into aspect ratio, and the present invention does not limit concrete implementation mode.

Step S260 determines that the pixel belongs to pending area, according to the ellipse circle of the pixel and pending area Equivalent circumferential distance between the heart determines translation distance information corresponding with the pixel, according to translation distance information by the picture Vegetarian refreshments moves to target location.

If judging, the equivalent circumferential distance between the pixel and the oval center of circle is not more than the length of the oval longitudinal axis, determines The pixel belongs to pending area, then is handled the pixel according to preset translation rule.

Specifically illustrate the method for the present invention, ability in the present embodiment by taking pending area is oval pending area as an example Field technique personnel are not it is understood that the present invention limits the region shape or profile of pending area, then accordingly Ground, judges whether pixel belongs to the mode of pending area and determine the mode of the corresponding translation distance information of pixel It is different due to the difference of the region shape of pending area.For example, for the application that pending area is round pending area Scene, judges whether pixel belongs to pending area and be specially：Judge the region of the pixel and the circle pending area Whether the distance between center of circle is more than the length of the zone radius of the circle pending area, if not, it is determined that the pixel category In pending area.Further according to the pixel and the determining corresponding translation distance information in the distance between the region center of circle, root Translation processing is carried out to pixel according to translation distance information.

Described in the above, the mode of translation distance information corresponding with pixel is determined in the present embodiment Further comprise：It is determining corresponding with the pixel with the distance between the regional center of pending area according to the pixel Translation distance information.

Specially：When the distance between the regional center according to the pixel and pending area determines that the pixel belongs to When target treatment, handles rule according to preset target and determine translation distance information corresponding with the pixel；Work as root When determining that the pixel belongs to environmental treatment region according to the distance between regional center of the pixel and pending area, according to Preset environmental treatment rule determines translation distance information corresponding with the pixel.

If that is, judging the length of the distance between the pixel and the oval center of circle no more than the oval longitudinal axis, i.e., The pixel belongs to pending area, further judges whether the pixel belongs to target treatment, specifically judges the pixel Whether the distance between point and the target center of circle are not more than the length of the target longitudinal axis or target horizontal axis, if it is not, determining the pixel Belong to target treatment, then handling rule according to preset target handles the pixel；If so, determining the pixel Point belongs to environmental treatment region, then is handled the pixel according to preset environmental treatment rule.

Correspondingly, when pending area is oval pending area, according to the area of the pixel and pending area The distance between domain center determines that the step of whether pixel belongs to target treatment specifically includes：

Judge whether the equivalent circumferential distance between the pixel and the oval center of circle is more than the length of the target longitudinal axis；If it is not, Determine that the pixel belongs to target treatment；If so, determining that the pixel belongs to environmental treatment region.

Further, if judging, pixel belongs to target treatment, according to preset target handle rule determine with The corresponding translation distance information of the pixel；If judging, pixel belongs to environmental treatment region, at preset environment Reason rule determines translation distance information corresponding with the pixel.

Wherein, target processing rule and environmental treatment rule can determine in the following manner：

It predefines when the equivalent circumferential distance in pixel to the oval center of circle is not more than the length of the target longitudinal axis, pixel Corresponding translation distance information and the pixel is to the first mapping relations between the equivalent circumferential distance in the oval center of circle, and mesh Mark processing rule is determined according to first mapping relations；It predefines when the equivalent circumferential distance in pixel to the oval center of circle is more than The length of the target longitudinal axis and when less than the length of the oval longitudinal axis, translation distance information corresponding to pixel and the pixel are to ellipse The second mapping relations between the equivalent circumferential distance of the round heart, and environmental treatment rule is determined according to second mapping relations.

Wherein, the first mapping relations can be determined according to the first translation distance look-up table, the first translation distance look-up table Horizontal axis represent pixel to the equivalent circumferential distance between the target center of circle, the longitudinal axis represents the translation distance of pixel, and first is flat Move apart from look-up table may indicate that the different corresponding translation distance of multiple pixels of the equivalent circumferential distance in the oval center of circle it Between difference, and the mapping principle of the first mapping relations is as follows：When the equivalent circumferential distance of pixel to the target center of circle is little When the length of the target longitudinal axis, during the equivalent circumferential distance between pixel and the target center of circle changes from small to big, pixel The translation distance of point is first maintained at a fixed value, is then gradually reduced from the fixed value, it is possible thereby to ensure untreated Region and treated region between transition be smooth.

Second mapping relations can be determined according to the second translation distance look-up table, the horizontal axis of the second translation distance look-up table Pixel is represented to the equivalent circumferential distance between the target center of circle, the longitudinal axis represents the translation distance of pixel, the second translation distance Look-up table may indicate that the difference between the different corresponding translation distance of multiple pixels of the equivalent circumferential distance in the oval center of circle It is different, and the mapping principle of the second mapping relations is as follows：When the equivalent circumferential distance of pixel to the oval center of circle is vertical more than target The length of axis and when less than the length of the oval longitudinal axis, during changing from small to big at a distance from pixel is between the target center of circle, The translation distance of pixel is gradually reduced from a fixed value, can ensure untreated region and warp through the above way It crosses between the region of processing with smooth transition.In addition, the method for the present embodiment is corresponding by the way that different disposal region is arranged Object handles rule can promote the aesthetic feeling of image to the change trace of weakening image.In order to make it easy to understand, Fig. 5 shows one The schematic diagram of the translation distance look-up table of kind of form, as shown in figure 5, for the pixel in pending area, pixel with During equivalent circumferential distance between the target center of circle changes from small to big, the rotation angle of pixel is first maintained at a fixation Value, then be gradually decreased as zero by the fixed value, wherein R can specifically refer to the oval longitudinal axis or horizontal axis of oval pending area Length.In addition, it will be appreciated to those of skill in the art that target, which is arranged, in the present invention handles regular and environmental treatment rule Purpose is：Target treatment and environmental treatment region are distinguished and treated, so as to which smooth transition is better achieved, Therefore, the present invention does not limit particular content (i.e. the first mapping relations and the of target processing rule and environmental treatment rule The concrete form of two mapping relations can be adjusted flexibly).Then, which is moved to by target position according to translation distance information It sets, specifically, according to translation distance information and the original coordinates value of the pixel, calculates the coordinates of targets value of the pixel； Target location is determined according to coordinates of targets value, which is moved into target location.

Wherein, it carries out translation processing to pixel to carry out in original image, that is, is directed to each in pending area A pixel determines that the corresponding translation distance of pixel is believed according to the equivalent circumferential distance between the pixel and the oval center of circle Breath, determines target location, and pixel is moved to mesh according to the original coordinates value of translation distance information and the pixel The coordinate value of the pixel can be by being assigned to the pixel realization positioned at the target location by cursor position.In addition, to pixel Point carries out the blank image that translation processing can also be created according to original image and newly and realizes, specifically, according to coordinates of targets value The step of determining target location, which is moved to target location specifically includes：It is pre-created corresponding with original image Blank image, target location is determined according to coordinates of targets value in blank image.

Which is establishment blank image corresponding with original image, is clicked through to pixel included in blank image The operation of row pixel value assignment, since the coordinates of targets value of pixel is calculated according to the original coordinates value of the pixel , therefore, the coordinate system in the blank image is consistent with the coordinate system needs in the image, ensures determining target with this The accuracy of position.It follows that according to which, for the pixel for being not belonging to pending area in image, target is sat Scale value is consistent with original coordinates value, and the pixel value of the pixel is directly assigned to target position corresponding positioned at the coordinates of targets value Set the pixel at place；For the pixel for belonging to pending area in image, then need according to corresponding with pixel Translation distance information determines target location, and the pixel value of the pixel is assigned to the pixel positioned at the target location.

Further, in order to adapt to the application scenarios of a variety of different image procossings, for example, when deal with objects for first with And when the second eyes, in order to reduce a spacing, need to move first eye position and the second eyes to centre It is dynamic, therefore, after the translation distance of pixel is determined, it is also necessary to the translation direction of pixel is determined, in addition, due to first Translation distance look-up table and the second translation distance look-up table define the corresponding pass between equivalent circumferential distance and translation distance System, and be fixed, and in practical applications, it generally requires to be modified translation distance information according to actual conditions, move The translation distance information for adjusting to state pixel reaches better treatment effect with this.It is further sharp in the present embodiment based on this The corresponding translation distance information of pixel is modified with modifying factor.

Specifically, between the regional center according to the pixel with pending area at a distance from determine with the pixel phase After the step of corresponding translation distance information, further comprise：

According to default translation modification rule, modifying factor corresponding with the pixel is determined, according to modifying factor to this The corresponding translation distance information of pixel is modified, and obtains translation update information；Then according to translation distance information by the picture Vegetarian refreshments moves to the step of target location and specifically includes：The pixel is moved into target location according to translation update information.Its In, modifying factor further comprises：Lateral modifying factor and longitudinal modifying factor.

Wherein, modifying factor is used to determine the translation direction of pixel and/or the translation amplitude of pixel, and modifying factor Son can be dynamically adjusted according to actual conditions, then in concrete application, can calculate pixel according to following formula Coordinates of targets value：

X=x '+x_scale*L

Y=y '+y_scale*L

Above-mentioned formula, which is shown, is modified translation distance information using lateral modifying factor and longitudinal modifying factor, The mode of coordinates of targets value is calculated according to revised translation distance information, wherein L is to be put down according to what equivalent circumferential distance determined Move distance；X_scale is lateral modifying factor, and y_scale is longitudinal modifying factor, indicate respectively pixel horizontal direction with And the translation amplitude on longitudinal direction, and absolute value is bigger, then and translation amplitude is bigger, if x_scale is positive value, table in addition Direction translation of the bright pixel on horizontal direction shows pixel on horizontal direction if x_scale is positive value Negative sense direction translates, and y_scale is similarly；X ' is the original abscissa value of pixel, and y ' is the initial ordinate value of pixel；x For the target lateral coordinates value of pixel, y is the target ordinate value of pixel.

The coordinates of targets value that pixel is determined according to above-mentioned formula then further determines that the corresponding target of coordinates of targets value The pixel value of the pixel is assigned to the pixel positioned at the target location, until to every in pending area by position One pixel has all carried out translation processing, then completes the operation translated to the process object in image.

It follows which can achieve the effect that a kind of process object in image translates；Next, according to Process object in image determines corresponding pending area so that pending area can be with the profile or shape of process object Shape is more bonded, and in face image processing scene, setting the region shape of pending area to ellipse can make to wait locating Reason region is more matched with face or face position；Secondly, which is without handling all pixels point in image, only It is handled for the pixel in pending area, operand can be reduced, promote the speed of image procossing；In addition, will wait for Processing region is divided into target treatment and environmental treatment region, and different pairs is taken for the pixel in different disposal region As processing rule, is conducive to the variation trace for weakening image, promotes the aesthetic feeling of image；It finally, can dynamic using modifying factor Ground adjusts the corresponding translation distance information of pixel, can obtain better treatment effect, be used in a variety of different applied fields Scape.
