The colour of skin adjustment of picture.
It should be noted that it is discontinuous in order to avoid what is adjusted to color, colour of skin mask images can be sprouted wings, obtained
To image as shown in Figure 2 b, colour of skin likelihood image is used as.When likelihood score is 1, area of skin color is properly termed as, when likelihood score is
When 0, non-area of skin color is properly termed as.Likelihood score is considered as transitional region between 0-1, using compromise color adjustment side
Case, it is to avoid discontinuous false texture occur.
Further, terminal is obtained after colour of skin likelihood image, and suitable two-dimensional color space can be selected to be handled.It
So choosing two dimension, is desirable to avoid the influence of brightness, the skin brightness in different photographic works there may be larger difference after all.
Wherein, two-dimensional color space includes one below：(one kind in color space, Y represents concentration, Cb and the Cr of light to YCbCr space
For blueness and red concentration excursion amount composition) in aberration CbCr；Tone saturation degree lightness (Hue Saturation
Value, HSV) tone saturation degree HS in space (one kind in color space)；Tone saturation degree brightness (Hue
Saturation Intensity, HSI) tone saturation degree HS in space；Tone saturation degree brightness (Hue Saturation
Brightness, HSB) tone saturation degree HS in space；Chromaticity a* and b* in CIE1976L*a*b* color spaces；Hunter
Chromaticity a and b in Lab (Hunter Lab) color space；Colourity uv in Luv spaces；CIE1931XYZ color standards are defined
Chromatic value x and y；Chromatic value r and b that CIE1931RGB color standards are defined.
Optionally, terminal can select colour of skin likelihood score>80 region calculates average colour of skin value of chromatism (Cbavg,Cravg),
Then the average colour of skin and preference skin tone value (that is, efficacy parameter) (Cb are calculatedprefer,Crprefer), for any one in picture
Pixel, new color value (Cbout,Crout) can be expressed as：
(Cbout,Crout)=(Cbin,Crin)+(Cbprefer-Cbavg,Crprefer-Cravg)·w·wg
Wherein, w is skin likelihood angle value, and different pixels have different likelihood scores.wgIntensity, w are adjusted for the global colour of sking∈
[0,1], whole pixels all share this parameter, wg=0 represents not adjust the colour of skin, wg=1 represents maximum adjustment intensity, value
Bigger adjustment intensity is bigger.This mode is equally applicable to the processing under the ab color spaces in Lab above.
Optionally, terminal can also select to adjust the colour of skin by tone (also known as form and aspect) saturation degree.Due to HSV, HIS and
Saturation degree adjustment in the color spaces such as HSB multiplies sexual intercourse, and processing mode slightly has difference.Therefore, terminal selects the colour of skin seemingly
So spend>80 region calculates average colour of skin value of chromatism (Hueavg,Satavg), then calculate the average colour of skin and preference skin tone value
(Hueprefer,Satprefer), for any one pixel in image, new color value (Hueout,Satout) can be expressed as：
Wherein, w is skin likelihood angle value, and different pixels have different likelihood scores.wgIntensity, w are adjusted for the global colour of sking∈
[0,1], whole pixels all share this parameter, wg=0 represents not adjust the colour of skin, wg=1 represents maximum adjustment intensity, value
Bigger adjustment intensity is bigger.This mode is equally applicable to the processing under the ab color spaces in Lab above.
Further, the above method is equally applicable to the processing under the tone saturation degree plane under the spaces such as HIS, HSB.
It is understood that terminal according to user colour of skin preference to Target Photo carry out colour of skin adjustment before, in advance
The operation of the efficacy parameter of foundation and the corresponding relation of display parameters can be：
Terminal can collect a large amount of quality and meet the aesthetic portrait photo of main flow first, below with India women auto heterodyne mobile phone
Colour of skin preference exemplified by, first collect India's wedding photography of more than 100, and count the aberration distribution of bride's colour of skin.Such as Fig. 3 a, system
Ji Liao287Zhang India wedding photography bride's skin value of chromatism (Cb, Cr).It can be found that in (Cb, Cr) plane, sample point approximately falls
Inside an ellipse, wherein, oval long axis direction embodies larger colour of skin preference span.Optimization Solution can be passed through
Mode, calculates elliptic equation, can also manually draw ellipse so that ellipse comprising most sample point and area as far as possible
It is small.80% sample point is included for example, solving, minimum ellipse equation is sought.Computational methods are as follows:
Elliptic focus coordinate is solved first, and it is f to make elliptic focus coordinate1, f2, then using Optimization Solution.Specially：
Make any one sample point siTo oval bifocal coordinate f1、f2Distance and be：So as to obtain expression formula：(f1,f2)=Argmin (Dsum(f1,f2)).During Optimization Solution,
(f can be set1, f2) initial value be sample set center of gravity.
As shown in Figure 3 b, because ellipse is to the distance of two focuses and (being represented with d) minimum track, then terminal-pair
Sample point is to above-mentioned focal length and is ranked up from small to large, just arranges 80% critical point and (uses pkRepresent) sample point arrive
The distance of two focuses and (use dkRepresent), exactly need solve distance and, so that f1、f2、dkThe side of ellipse is uniquely determined
Journey.
In order to simplify system, difference of the colour of skin preference in ellipse short shaft direction can be ignored, it is only necessary to provide the user with people
Machine interactive interface, user can adjust the colour of skin according to hobby in long axis direction.Further, can be by the skin tone value of preference about
Beam is on the line segment between elliptic focus.In CbCr aberration planes, preference colour of skin track is a line segment, as shown in Figure 3 b.
Specifically, assuming skin brightness value Y=128, then terminal can be in YCbCr color spaces and HSV color spaces
Converted, obtain tone (Hue, H) and saturation degree (Saturation, S) value.Wherein, specifically can CbCr preference skin
5 points uniformly are taken on color track, as shown in Figure 3 c, and HSV spaces are converted to, (i.e. effect is then drawn out shown in trajectory diagram 3d
Parameter trajectory figure).These can also be put by fitting tool (excel) and carry out fitting of a polynomial, it is as shown in Figure 3 e, multinomial
The expression of formula can be：Y=8E-05x2-0.0012x2+0.0152x+0.1203.So far, we obtain colour of skin preference track
(efficacy parameter track), in embodiments of the present invention, the colour of skin adjustment of user can be all constrained on colour of skin preference track.
If, can be with pulling when user pulls slider bar corresponding with efficacy parameter in the CbCr space allocation colours of skin
Aberration is adjusted apart from equal proportion.If, can be slightly more complicated in saturation degree-tone space adjustment colour of skin, when user pulls
During slider bar corresponding with efficacy parameter, tone (HUE) can be adjusted with pull distance equal proportion, and with adjustment saturation degree
(SAT) distance, can also be pulled on and do equal proportion mapping with the distance to above-mentioned preference track starting point.2 points of distance on track
It can be obtained by curve integral and calculating.User can also set efficacy parameter value, according to multinomial correspondence calculate tone and/
Or the value of saturation degree.
Permission Constraints user adjusted due to this programme are on preference colour of skin track, no matter the style that user adjusts is such as
What, can better conform to colony's preference, the probability for meeting user oneself preference is also greatly increased.Therefore, user can be quickly
Area of skin color part in picture is adjusted according to the colour of skin preference of oneself, the efficiency to picture processing is improved.
As another feasible embodiment, terminal is after target display parameters are determined, according to target display parameters
Adjusting the concrete mode of Target Photo can be：It will be close to like the color of skin tone value (target effect parameter) to be adjusted so as to more connect
The skin tone value closely liked, it is furthermore appreciated that being that the display parameters that will be close to target display parameters (are referred to as to be adjusted
Display parameters) it is adjusted so as to closer to target display parameters.Closer to the intensity of adjustment is bigger, as shown in fig. 4 a.Wherein, wait to adjust
Whole display parameters can use mahalanobis distance to calculate with target display parameters close to degree, and mahalanobis distance is shorter, the power of adjustment
The w that weighs is again bigger.Shown in specific adjustment mode equation below：
Wherein, (ain,bin) represent original point coordinates, (aprefer,bprefer) represent the colour of skin liked, (aout,bout) represent
Skin tone value after adjustment.wgIntensity, w are adjusted for the global colour of sking∈ [0,1], whole pixels all share this parameter, wg=0 table
Show and do not adjust the colour of skin, wg=1 represents maximum adjustment intensity, is worth bigger adjustment intensity bigger.W represents weight, and weight is bigger,
The intensity of adjustment is bigger.W can be the inverse of mahalanobis distance (Mahalanobis distance).Wherein, mahalanobis distance according to
A large amount of photo colour of skin samples, which are calculated, to be obtained, and can also be calculated and be obtained by way of shown in Fig. 4 b.In fig. 4b, current pixel face
Chromaticity coordinates is closer to the oval border of skin distribution, and weight w is smaller, closer to hobby colour of skin point, and weight is bigger, current pixel color
Such as fall beyond skin distribution is oval or just fall on border, w=0.
Optionally, terminal adjusts the specific of Target Photo after target display parameters are determined according to target display parameters
Mode can also be：Selection adjusts the colour of skin by tone (also known as form and aspect) saturation degree.Due to color spaces such as HSV, HIS and HSB
In saturation degree adjustment multiply sexual intercourse, processing mode slightly has difference.Remember preference skin tone value (Hueprefer,Satprefer), it is right
Any one pixel in image, new color value (Hueout,Satout) can be expressed as：
Wherein, (Huein,Satin) represent original skin tone value, (Hueavg,Satavg) represent average skin tone value.It is above-mentioned
Hue (tone or form and aspect) and Sat (saturation degree or color density) can be：Tone saturation degree HS in HSV space；HSI
Tone saturation degree HS in space；Tone saturation degree HS in HSB spaces.
Further, color (each display parameters) has been tied to a curve by terminal through the above way, therefore can be with
It is a variable, i.e. efficacy parameter by above-mentioned display parameters dimensionality reduction.
Further, efficacy parameter can be mapped on slider bar.As illustrated in fig. 4 c, the thumbnail shown on slider bar
Directly mapped one by one with efficacy parameter, when slider bar is just directed at one of thumbnail, efficacy parameter is exactly right on track
The parameter answered, according to the mapping relations between efficacy parameter and display parameters, may thereby determine that out that each shows display ginseng
