Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
It will the technical scheme of the embodiment of the invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Referring to FIG. 1, it is the flow chart of the method provided in an embodiment of the present invention to picture character moulding.The present embodiment
Various intelligent terminals, including smart phone, tablet computer, mobile Internet are mainly used in the method for picture character moulding
Equipment (MID, Mobile Internet Device), laptop etc..
As shown in Figure 1, the method to picture character moulding, comprising:
Step S101: the head zone of picture personage and the key point of head zone are detected.
For actual conditions, character image design body parts, but mainly for human body in this programme
Head carries out moulding, therefore detects in the method mainly for the head of picture personage, without regard to picture people in picture
Other positions of object.The detection of specific head zone is determined based on recognition of face.
Become specifically, feature workable for recognition of face is generally divided into visual signature, pixels statistics feature, facial image
Change coefficient characteristics, facial image algebraic characteristic etc..Face characteristic extraction is carried out aiming at certain features of face.Face is special
Sign is extracted, and also referred to as face characterizes, it is the process that feature modeling is carried out to face.The method that face characteristic extracts is summed up point
For two major classes: one is Knowledge based engineering characterizing methods；Another is the characterizing method based on algebraic characteristic or statistical learning.
Knowledge based engineering characterizing method mainly according to the shape description of human face and they the distance between characteristic
The characteristic for facilitating face classification is obtained, characteristic component generally includes Euclidean distance, curvature and angle between characteristic point
Degree etc..Face is locally made of eyes, nose, mouth, chin etc., and to these parts and the geometry of structural relation is retouched between them
It states, can be used as the important feature of identification face, these features are referred to as geometrical characteristic.Knowledge based engineering face characterizes
Method and template matching method based on geometrical characteristic.
Complete recognition of face has higher requirement for the precision of data processing and the performance of hardware, and in we
In case, the detection of head zone is not related to accurately identify face, head zone need to only be positioned, then to this
Moulding is carried out, therefore the difficulty series of image procossing is lower, the specifically also positioning only to the key point of head zone.
Step S102: obtaining moulding material, reads the key point in moulding material.
The pre-stored moulding material for head modeling is obtained, moulding material is processed into the size of standard, mark
Quasi- format is directly covered in corresponding position when being head zone fusion.
The key point of the moulding material: being corresponded to the key point of the head zone by step S103, and handle modeling material melts
Close head zone.
In step s101, during identifying head portrait, the position of the key point of head zone is just had been obtained for,
And the position of key point is also carried in pre-stored moulding material, the position of the key point of the two confirm after corresponding to
Then moulding material is fused to head zone by the position of head zone of the moulding material in picture, complete picture personage and make
The process of type.
In conclusion the embodiment of the present invention passes through the head zone detected in photo automatically, to the key of head zone
Point is positioned, and moulding material is fused to the existing corresponding moulding of personage in head zone replacement photo according to key point, is
User's selection is suitble to the moulding material of oneself to provide strong reference, can mention when carrying out moulding collocation design for user
For reference, easy to operate time saving, and generate directly against user with reference to figure, sculpting method can be straight to the effect of self-image
It sees and presents.
Referring to FIG. 2, it is second embodiment of the method provided in an embodiment of the present invention to picture character moulding
Method flow diagram.The present embodiment and the main distinction of method one embodiment are, further illustrate head zone detection
Process is specifically fused to the detailed process of head zone to the positioning of key point and moulding material in the detection process.
As shown in Fig. 2, the method to picture character moulding, comprising:
Step S201: confining the head zone of picture personage, marks the key point of face, and the key point of face includes two
Key point.
In order to enable the fusion of the moulding material of the identification and later period of head zone can standardize progress, picture is confined
The head zone of personage is face to be placed in the center for confining range using face as reference, and mark the key point of face, five
The key point of official includes two key points, and the position of key point is that the spin balancing of head zone in subsequent step adjusts, is big
The fusion of the ratio, moulding material of small scaling has critical reference role.
Certainly, mouth might not also may be selected using two key points as unique selection in the key point of the face
Key point, the key point of nose, the key point of two ears, further, place between the eyebrows, face central axes key point be chosen as closing
Key point, but generally for the ease of identifying and calculating simplicity, two points when selecting just to put on horizontal or vertical direction are as pass
Key point, that is, corresponding face key point or the point on central axes.
Step S202: when the size difference of face left in head zone and right face is less than threshold value, picture is revolved
Turn, so that the line of two key points is in level.
People may show a variety of different postures during actual take pictures, and optimal presentation mode is to shine naturally
Head is just presented positive face in piece, and the line of place between the eyebrows and the bridge of the nose is exactly central axes, and the line of two key points is just horizontal,
But such case be after all it is a small number of, there are many postures to will cause in picture character facial with a kind of not right in true picture
The mode of title is presented, such as amesiality, and head zone can be in as emphasis using the face of certain side in picture at this time
It is existing, if also carrying out character moulding in this case in the method for positive face, the picture after moulding can be allowed to generate uncoordinated,
Such as be one originally and have the hair style class moulding material of fringe, but an amesiality picture is provided, at this time such as
Moulding material is fused in picture by fruit by force, and the position of fringe will shift, the side in face, influences moulding effect
Fruit.Therefore only guarantee that the difference of left face and right face is less than threshold value.Specific threshold value can be determined according to actual modeling requirement,
Such as 6%, 8%, 10%, threshold value is bigger, and the requirement of precision is lower, when there is the case where being greater than threshold value, then needs to provide new
Picture.Existing mobile terminal all comes with picture taking lens, thus generates a kind of shirtsleeve operation mode, directly reacquires
Picture, because only need to be to head modeling, moulding have great changes after playing compared with original picture, thus only need by
Camera lens face head, shoots the photo of head zone.
When confirming that the size difference of left face and right face is less than threshold value in head zone, that is, confirm the deflecting angle on head
Angle value is needed to carry out first time adjustment to picture at this time, picture be rotated, so that described within the scope of acceptable
The line of two key points is in level.Target rotation in the step can be selected according to actual needs.One is only
Within the scope of rotation is confined, that is, the picture of head zone, another kind are the entire pictures of rotation.Two methods have their own advantages,
Former picture range to be treated is smaller, need to only handle the pixel of head zone, and the pressure of picture processing is smaller；
The operating procedure of latter is more succinct, directly operates to whole picture, without individually plucking out head zone.The two can
To be selected according to the actual treatment ability of mobile terminal and the size of picture.Such as high definition picture selects former, commonly
The picture of quality or lesser picture select former.
Because this programme is that two materials are merged, it is possible to be that a side adapts to another party, be also possible to another party
Adapt to a side.As another party of fusion, moulding material can also make corresponding rotation so that the line after rotation between key point with
The line of corresponding key point is parallel in picture.
Step S203: picture is zoomed in and out, so that the standard of the size of the head zone confined and moulding material
Head zone size is adapted.
In order to which head zone is carried out merging for high quality with moulding material, the standard of a fusion is needed, suitable
Position merged, the generation process of this standard is actually the process for carrying out scaled and both to adapt to.
The adaptable adjustment of specific size can be there are many processing mode.Such as when confining head zone, model is confined
Enclose be one with moulding material the consistent box of length-width ratio, moulding material be 400 × 400, i.e. 1:1；So confining head
It when region, is then confined, such as 200 × 200 or 600 × 600, is then zoomed in or out to 400 × 400 by the side ratio of 1:1
Subsequent processing is carried out again.Another processing mode is directly zoomed in and out by key point, as the key in certain moulding material clicks
Be two key points, the distance between two key points are 200, and two in the key point for the head zone that detected
Key point distance be 150, then by picture amplify 1/3 so that in the key point of head zone two key points distance
200 are enlarged by 150；, whereas if the distance of two key points is 400 in the key point for the head zone that detected,
Picture is then reduced 1/2, so that the size for the head zone confined and the standard head area size of moulding material be allowed to be adapted.
Similar with the rotation in previous step, the scaling in this step can be picture scaling and be adapted with moulding material,
It can be moulding material scaling to be adapted with picture.
Step S204: obtaining moulding material, reads the key point in moulding material.
The type of the moulding material includes forming hair material, and forming hair material includes masking-out figure, in the masking-out figure
Visibility region portray hairline, be provided with key point coordinate in the masking-out figure, which indicates hairline phase
For the position of face key point.
A kind of pair of moulding material is mentioned in step S202 and step S203 to be changed to adapt to the implementation process of picture,
Corresponding with this embodiment, this step needs first to obtain moulding material toward premise, grasp to moulding material
Make.
Masking-out figure therein is all-transparent, will not influence picture after fusion, and hairline therein then can after fusion
Original content of coverage diagram on piece.
Step S205: by the key point coordinate setting in the masking-out figure of the moulding material to the corresponding head zone
Key point, masking-out figure is merged into head zone.
In step S203, for picture scaling there are two types of mode, one is picture is based on, one is based on key
Point.The wherein comparatively relatively good operation of the fusion based on key point, because of the pass in key point and moulding material in picture
Key point can be completely coincident after the zooming, it is only necessary to be corresponded to two o'clock, can be confirmed that moulding material corresponds to picture
In position, easily realize fusion.And the mode merged after being scaled for another kind to picture, then it is relatively complicated, still
The effect of fusion can be more preferable simultaneously, because the ratio of the face of everyone shape of face is different, if only with wherein one group of pass
Key point is reference, then will appear the situation that ratio is uncoordinated after merging, so in the implementation process amplified to picture, because of figure
The piece coincidence in the same size for not necessarily bringing key point position, only need at this time by the center of the key point in picture with make
The center of key point in type material is overlapped, that is, can determine the position of fusion, and modelling element and head in picture after fusion
The ratio in region is more coordinated.
Step S206: picture is zoomed in and out, so that the picture is restored to initial size.
In the present embodiment, be restored to guarantee fused moulding material in picture it is undistorted after initial size,
The picture for the high density pixel that moulding material all provides, can guarantee enough display effects, Jin Er after zooming in and out
Guarantee that good effect is presented in picture after obtained moulding.It is last that scaling in the present embodiment does not interfere with picture not only
Effect, instead because of the high density pixel of moulding material, after capable of still guaranteeing not occur in picture picture amplification after fusion
The case where distortion, embodies most true moulding additive effect.
Step S207: picture is rotated, so that angle is extensive between the line and horizontal line of two key points
Initial angle is arrived again.
Step S206, the operation of step S207 with before the step of in step S203, the operation of step S202 it is corresponding, this
Place repeats no more, it should be noted that step S203, step S202 operation in, there are also a kind of preferred scaling, rotations to make
The mode of type material, if in front of the step of being the mode for selecting scaling, rotational moulding material, step S206 and step
Suddenly S207 is no existing necessary, and moulding material, which is directly fused in picture, can be completed moulding.
In order to be further illustrated to the hair style fusion process in this implementation, modeling process is carried out in conjunction with Fig. 3 to Fig. 9
More specifically illustrate.It is the head portrait Local map in a picture as shown in Figure 3, head portrait is not horizontal in the initial state, but
It is to need the head zone being placed in center when confining head zone, the size after the head zone scaling confined
As shown in figure 4, key point can also be readily available after confining out head zone, so that it is determined that the angle that needs to rotate,
Dotted line between two key points as shown in Figure 4 is the reference line rotated, and dotted line is made to be in level after rotation,
It is specific as shown in Figure 5.Slightly distinguishing in describing with abovementioned steps is first to carry out the scaling of size here, carry out angle afterwards
Rotation, but for the processing result of event be do not have it is influential.After adjusting the size of head zone, moulding is obtained
Material, two moulding materials as shown in figures 6 and 7, hairline therein are visibility region, and other parts are transparent
Masking-out, each moulding material include crucial location information, specially coordinate.It obtains and confines and reduce shown in Fig. 5
It, will according to the location information of the key point of the two after moulding material shown in postrotational head portrait region and Fig. 6 and Fig. 7
Moulding material covers head zone.Special emphasis is, fusion when is not that head zone figure and masking-out figure is complete
Merged after overlapping, but carry out the overlapping of selectivity according to the location information of key point, that is, only overlapped, it is general and
Speech, marginal portion has seldom a part and is not overlapped.As for it is subsequent by scale and rotate restore size and angle with
Operation before is similar, is no longer described in detail, and the effect picture after finally obtaining moulding as shown in Figure 8 and Figure 9 corresponds respectively to figure
Moulding material schematic diagram described in 5 and Fig. 6.In order to enhance syncretizing effect, the part that part therein fails to be completely covered is done
Removing processing because this operation in existing graph and image processing using quite a lot of, technology is also very mature, therefore do not make
It further illustrates.
In conclusion the embodiment of the present invention is detected and is confined to the head zone in picture, the header area that will be confined
The range in domain is rotated and is scaled, make its with require size and Orientation consistent, convenient for fusion.And it is preferred that a kind of adjustment is made
The mode that type material is adapted it with picture operates more convenient.Certainly, two different adjustment modes are subsequent is corresponding with not
Same operating procedure, but moulding, which can play good effect, to be achieved the purpose that for fusion.Generally speaking, by examining automatically
The head zone in photo is measured, the key point of head zone is positioned, moulding material is merged to the end according to key point
The existing corresponding moulding of personage in photo is replaced in portion region, is suitble to the moulding material of oneself to provide strong ginseng for user's selection
It examines, reference can be provided when carrying out moulding collocation design for user, it is easy to operate time saving and raw directly against user
At with reference to figure, the effect of self-image can be intuitively presented in sculpting method.
Referring to FIG. 10, it is the third embodiment of the method provided in an embodiment of the present invention to picture character moulding
Method flow diagram.The present embodiment and the main distinction of second embodiment of method are, are further provided with a variety of different make
Type material, and the method for once completing multiple moulding.

Step S301: moulding material is prestored.
The type of the moulding material includes forming hair material, and forming hair material includes masking-out figure, in the masking-out figure
Visibility region portray hairline, be provided with key point coordinate in the masking-out figure, which indicates hairline phase
For the position of face key point；These restrictions are to there is a reference when being merged.And for modelling element
For, other than hair style, other are suitable for the moulding material of head zone it is contemplated that so the type of moulding material is also wrapped
Beard moulding material, eyebrow moulding material, glasses moulding material are included, certainly also not only includes these types.
Step S302: confining the head zone of picture personage, marks the key point of face, and the key point of face includes two
Key point.
Preferably, the key point of the face further includes the key point of mouth, the key point of nose, the key point of two ears.
More specifically, the coordinate of the key point of the mouth such as corners of the mouth, the key component example of the coordinate of the key point of the nose such as bridge of the nose, two ears
Such as the coordinate of two ear ear-lobes.
Step S303: when the size difference of face left in head zone and right face is less than threshold value, picture is revolved
Turn, so that the line of two key points is in level.
It is that during actual implementation, also can be selected using two key points as the key point of face in the step
Other key points, it might even be possible to which it is suitable with one later to make comprehensive analysis to it for the key point for further selecting a variety of face
Ratio moulding material is fused in picture.
Step S304: picture is zoomed in and out, so that the standard of the size of the head zone confined and moulding material
Head zone size is adapted.
Step S305: confirmation needs the type of the moulding material of moulding, obtains 9 kinds of moulding materials of the type.
Every possible more than one of one kind moulding material, if each requires to individually enter picture, the body of user
Testing will become very poor, therefore a variety of moulding materials are carried out batch reserves.Certainly, 9 kinds of moulding materials are also only a kind of preferred
Reference mode, can be more multiple, or less, such as 12,4.After the type for selecting moulding material, the specific aim of moulding is very
By force.
Embodiment as one preferred can ignore the type of moulding material in this step, directly acquire 9 kinds
Moulding material obtains moulding material at random, can occur hair style moulding material simultaneously in moulding material in 9, beard is made
Type material, eyebrow moulding material, glasses moulding material etc., the result of moulding more horn of plenty.
Certainly, 9 kinds of moulding materials are intended merely to that the size presented is more particularly suitable, arrange more neat and select a kind of excellent
Embodiment is selected, can be arranged in nine grids in the case where 9 kinds of moulding materials.If it is four kinds or 16 kinds, it is corresponding can
By using arranging in a manner of 2*2 or 4*4, for other numbers, can directly determinant is arranged from top to bottom, example
Such as, selection is 5 kinds of moulding materials, can be divided into 2 rows, and upper 3 lower 2 mode is arranged.Only practised according to the routine of people
It is used, it arranges by determinant.
Step S306: the key point of 9 kinds of moulding materials is corresponded to the key point of the head zone, handle modeling material respectively
It is fused to head zone.
Step S307: picture is zoomed in and out, so that the picture is restored to initial size.
Step S308: picture is rotated, so that angle is extensive between the line and horizontal line of two key points
Initial angle is arrived again.
Step S309: 9 kinds are merged the picture of moulding material, is shown in a manner of nine grids.
For 9 primarily directed to smart phone, and for other terminals, such as tablet computer, notebook, their screen
Curtain is enough big, can also select more multiple presented, but for general smart phone, 9 have been to present substantially
The limit, then be possible to not see, and nine grids are also the preferred embodiment to this.And for more pictures, it is in
Now result is not also just nine grids.
The presentation mode of nine grids, which is not to say that, only shows styling result, it is often more important that it is being presented with nine grids
Afterwards, user carries out preview to styling result, because some styling results are due to moulding material and figure in actual modeling process
The difference in size problem of original moulding of personage, can not be completely covered original moulding in piece, such as be originally explosion head, make
It is butch haircut in type material, in this case, modeling effect can't be fine, needs user to sieve styling result at this time
Choosing, unsatisfied styling result is deleted, corresponding, polishing nine after the one moulding material moulding of a reacquisition deleted
Gong Ge, to be supplied to the top quality styling result of user.
In conclusion the embodiment of the present invention, which further determines that, is further provided with a variety of different moulding materials, and one
The secondary method for completing multiple moulding will first select the type of moulding material before to picture moulding, then in this type model
It encloses and interior disposably carries out multiple moulding, naturally it is also possible to which selection once carries out moulding to multiple types, with nine palaces after moulding
The mode of lattice is presented.Generally speaking, by detecting the head zone in photo automatically, the key of head zone is clicked through
Moulding material is fused to the existing corresponding moulding of personage in head zone replacement photo according to key point, is user by row positioning
Selection is suitble to the moulding material of oneself to provide strong reference, can provide ginseng when carrying out moulding collocation design for user
It examines, it is easy to operate time saving, and generate directly against user with reference to figure, sculpting method can intuitively be in the effect of self-image
It is existing.
Figure 11 is please referred to, is the 4th embodiment of the method provided in an embodiment of the present invention to picture character moulding
