Example one
Referring to fig. 1, a flowchart illustrating steps of an image processing method according to a first embodiment of the present invention is shown, which may specifically include the following steps:
In the embodiment of the invention, an image to be processed is identified to obtain a lip region, for example, the image is subjected to face identification to obtain a face image, and the lip region is extracted from the face image by identifying the lip outline; or the lip recognition may be directly performed on the image to directly obtain the lip region, and any suitable recognition method may be specifically adopted, which is not limited in the embodiment of the present invention.
The parameters of the color of the lip region include Saturation, lightness, Hue, for example, S (Saturation), V (lightness), H (Hue) in HSV (Hue) color space.
In the embodiment of the invention, a large number of pixel points are arranged on the lip area, the saturation and the brightness of all or part of the pixel points on the lip area are detected, and the average value of the saturation and the brightness is calculated to obtain the average saturation and the average brightness of the lip area.
And 103, processing the lip area according to the average saturation and the average brightness.
Different average saturation and average lightness correspond to different lip region processing so as to beautify the lip region, and different processing can be adopted according to different lip colors, so that the requirement of different users for lip beautification is met.
In this embodiment of the present invention, processing the lip region according to the average saturation and the average brightness may include multiple implementation manners, for example, determining a target parameter range in which the average saturation and the average brightness are located, processing the lip region according to the target parameter range, or any other suitable implementation manner, which is not limited in this embodiment of the present invention.
For example, for a lip region where the average saturation and the average brightness are too high, the processing of reducing the average saturation and the average brightness is adopted, and for a lip region where the average saturation and the average brightness are both within an acceptable range, the original lip region may be directly output without any processing.
In the embodiment of the present invention, the processing may include processing of saturation, brightness, and sometimes hue, of an image. The lip area is subjected to image processing by this step so as to beautify the image.
In the embodiment of the invention, the lip region in the image to be processed is identified, the average saturation and the average brightness of the lip region are obtained, and the lip region is processed according to the average saturation and the average brightness, so that different processes can be adopted for different saturations and different brightnesses, the same image processing is not used for all lip colors, and the problem that a cut processing mode cannot be applied to all conditions is solved.
Example two
Referring to fig. 2, a flowchart illustrating steps of an image processing method according to a second embodiment of the present invention is shown, which may specifically include the following steps:
in step 201, a lip region in an image to be processed is identified.
In the embodiment of the present invention, the specific manner of this step may refer to the description in the foregoing embodiment, and is not repeated herein.
In the embodiment of the present invention, the specific manner of this step may refer to the description in the foregoing embodiment, and is not repeated herein.
In the embodiment of the present invention, the parameter range includes a range obtained by dividing parameters of two dimensions of saturation and brightness, and the parameter range may be defined according to statistics and experience, for example, the parameter range may be divided into a preset high-saturation high-brightness parameter range, a preset low-saturation low-brightness parameter range, a preset high-saturation low-brightness parameter range, a preset acceptable parameter range, and the like, or any other applicable range, which is not limited in this embodiment of the present invention.
For example, as shown in the parameter range division diagram of FIG. 3, four quadrants are divided according to two dimensions of saturation (denoted by S) and lightness (denoted by V), with the degree from high (denoted by H) to low (denoted by L). The middle part is a range in which the saturation and brightness of the lip region are in a relatively ideal range, namely a preset acceptable parameter range, and the other four regions respectively represent a preset high-saturation high-brightness parameter range (represented by HS-HV), a preset low-saturation high-brightness parameter range (represented by LS-HV), a preset low-saturation low-brightness parameter range (represented by LS-LV) and a preset high-saturation low-brightness parameter range (represented by HS-LV).
In the embodiment of the present invention, according to the average saturation and the average brightness, the parameter range in which the parameter is located can be determined and is recorded as the target parameter range.
And 204, processing the lip area according to the target parameter range.
In the embodiment of the invention, different target parameter ranges correspond to different treatments, and corresponding adjustment is made according to the color characteristics of the different target parameter ranges so as to be suitable for the lip region.
In the embodiment of the present invention, optionally, according to the average saturation and the average brightness, one implementation of processing the lip region may include: and determining an applicable display lookup table according to the average saturation and the average brightness, overlapping the display lookup table to the lip region, and outputting the processed lip region.
There are many ways to process the image, and here, a way of overlaying different display lookup tables (look up tables) is chosen to obtain the processed lip region.
In the embodiment of the present invention, optionally, according to the target parameter range, one implementation manner of processing the lip region may include: and if the target parameter range is a preset high-saturation high-brightness parameter range, reducing the brightness of the lip area and the saturation of a preset color.
According to statistics and experience, for the case that the target parameter range is the preset high-saturation high-brightness parameter range, the lip region may have applicability to reducing brightness and red saturation, where the preset color may be set according to actual needs, and the embodiment of the present invention is not limited thereto.
For example, the magenta and white in the magenta in the "optional colors" in the display lookup table are reduced, and the red in the white is increased to form LUT-1 (i.e., display lookup table No. 1), so that the lightness and the saturation of the red in the magenta are reduced for the color related to the magenta in the original color in the table, and after the LUT-1 is superimposed on the original lip area, the lightness and the saturation of the preset color in the lip area are reduced, thereby not only beautifying the lip color, but also preserving the hue of the lip area and avoiding the problem of the hue change of the human inverse sense of the coated red.
In the embodiment of the present invention, optionally, according to the target parameter range, one implementation manner of processing the lip region may include: and if the target parameter range is a preset low-saturation high-brightness parameter range, reducing the brightness of the lip region and improving the saturation of the preset color in the lip region.
According to statistics and experience, for the case that the target parameter range is the preset low-saturation high-brightness parameter range, the method has applicability to the lip region for reducing brightness and improving saturation of red, wherein the preset color can be set according to actual needs, and the embodiment of the invention is not limited to this.
For example, white in the 'optional colors' in the lookup table is displayed, black of the white is increased, cyan of the white is reduced to achieve the purposes of reducing lightness and changing pale lip color to ruddy, then saturation of red in the red is increased to form LUT-2 (namely, the lookup table No. 2 is displayed), so that original low-saturation red in the table becomes more saturated, and after the LUT-2 is overlapped on an original lip area, the lightness of the lip area is reduced and the saturation of a preset color is improved, so that the lip color beautifying effect is achieved, the original hue of the lip area is kept, and the problem that people who paint lipstick feel the hue change is avoided.
In the embodiment of the present invention, optionally, according to the target parameter range, one implementation manner of processing the lip region may include: and if the target parameter range is a preset low-saturation low-brightness parameter range, improving the brightness of the lip area and the saturation of preset colors, and adjusting the first preset hue in the lip area to be a second preset hue.
For the case that the target parameter range is the preset low-saturation low-brightness parameter range, it is applicable to the lip region to increase brightness and increase saturation of red, where the preset color may be set according to actual needs, and the embodiment of the present invention is not limited thereto. However, after the lightness is increased, the color unevenness is increased, and therefore, it is necessary to adjust the yellow-green color to an orange color to reduce the color unevenness and to beautify the color of the lips. The first preset hue and the second preset hue may be set according to actual needs, which is not limited in the embodiment of the present invention.
For example, white in the "optional color" in the display lookup table is increased, saturation of red is increased, and a yellow-green hue needs to be converted into an orange hue to form LUT-3 (i.e., display lookup table No. 3), and after the LUT-3 is superimposed on the original lip region, the effects of increasing lightness of the lip region and increasing saturation of a preset color are achieved, and then after the hue is adjusted, mottle in the lip color is reduced, so that the lip color becomes more beautiful.
In the embodiment of the present invention, optionally, according to the target parameter range, one implementation manner of processing the lip region may include: and if the target parameter range is a preset high-saturation low-brightness parameter range, improving the brightness of the lip area and reducing the saturation of the preset color.
For the case that the target parameter range is the preset high saturation low brightness parameter range, it is applicable to the lip region to increase brightness and decrease saturation of red, where the preset color may be set according to actual needs, and the embodiment of the present invention is not limited thereto.
For example, the curve highlights the red color in the 'optional color' in the display lookup table, and then the saturation of the red color is weakened to form LUT-4 (namely, the display lookup table No. 4), so that the original high saturation red color in the table is weakened, and after the LUT-4 is superposed on the original lip area, the lightness of the lip area is improved and the saturation of the preset color is reduced, thereby not only achieving the effect of beautifying the lip color, but also keeping the original hue of the lip area and avoiding the problem of the hue change which is disliked by people who paint the lip color.
In the embodiment of the present invention, optionally, according to the target parameter range, one implementation manner of processing the lip region may include: if the target parameter range is a preset acceptable parameter range, the lip region does not need to be processed.
In the embodiment of the invention, the lip region in the image to be processed is identified, the average saturation and the average brightness of the lip region are obtained, the target parameter range where the average saturation and the average brightness are located is determined, and the lip region is processed according to the target parameter range, so that different processes can be adopted for different saturations and different brightnesses, the same image process is not used for all lip colors, and the problem that a cut processing mode cannot be applied to all conditions is solved.
Further, if the target parameter range is a preset low-saturation high-brightness parameter range, the brightness of the lip area and the saturation of preset colors are reduced, or if the target parameter range is a preset low-saturation high-brightness parameter range, the brightness of the lip area is reduced, and the saturation of the preset colors in the lip area is improved, or if the target parameter range is a preset low-saturation low-brightness parameter range, the brightness of the lip area is improved, and the saturation of the preset colors is reduced, so that the original lip color beautifying effect is achieved, the hue of the lip area is also reserved, and the problem that people who paint lipstick feel the hue change reversely is avoided.
Further, if the target parameter range is a preset low-saturation low-brightness parameter range, brightness of the lip area and saturation of preset colors are improved, the first preset hue in the lip area is adjusted to be the second preset hue, the effects of improving brightness of the lip area and improving saturation of the preset colors are achieved, and then after the hue is adjusted, variegated colors in the lip colors are reduced, so that the lip colors are more attractive.
