Value obtains the XYZ of each grayscale of RGB under the default visual angle.
Specifically, default the 2nd 8 farmland of visual angle is obtained according to the XYZ of 0 grayscale of the one 8 farmland pixel under the default visual angle
The brightness value of 0 grayscale of pixel W, Y value is the default visual angle in the XYZ of 0 grayscale of the one 8 farmland pixel under the default visual angle
The brightness value of 0 grayscale of lower 2nd 8 farmland pixel W；It is obtained according to the XYZ of the one 8 farmland pixel preset gray scale under the default visual angle
The brightness value of 255 grayscale of 2nd 8 farmland pixel W under the default visual angle, the one 8 farmland pixel preset gray scale under the default visual angle
XYZ in Y value be the default visual angle under the 2nd 8 farmland pixel W 255 grayscale brightness value；Here preset at the one 8 farmland under visual angle
Pixel preset gray scale it can be selected that generally using the more larger grayscale of relative value, such as 250,251,252,253,254,
255。
In the case where obtaining the predetermined angle the 2nd 8 under the brightness value of 0 grayscale of the 2nd 8 farmland pixel W and the predetermined angle
After the brightness value of 255 grayscale of farmland pixel W, according to formulaCalculate the 2nd 8 farmland under the predetermined angle
The brightness value of each grayscale of pixel W, the c are the brightness value of each grayscale of the 2nd 8 farmland pixel W under the predetermined angle,

One corresponding relationship, the grayscale value and the grayscale value of R of the 3rd 8 farmland pixel W, the grayscale value of G, B grayscale value there is second pair
It should be related to.
It should be noted that carry out white balance on the one hand be required to meet gamma gamma=2.2 adjustment, on the other hand other
The corresponding chromaticity coordinates value x and y of grayscale W is equal with chromaticity coordinates the value x and y of 255 grayscale W respectively.
Before no progress blank level adjustment, the grayscale value and the grayscale value of R of W, the grayscale value of G, B grayscale value have
First corresponding relationship, the grayscale value of W and the grayscale value of R, the grayscale value of G, the grayscale value of B are all equal at this time, such as the grayscale value of W
It is 255, then the grayscale value that the grayscale value of R is 255, the grayscale value of G is 255, B is also 255.
After carrying out white balance, the grayscale value of W is corresponding with second with the grayscale value of the grayscale value of R, the grayscale value of G, B
Relationship, at this time the grayscale value of the grayscale value of W and R, the grayscale value of G, B grayscale value might not be essentially equal, can specifically join

| 103 | 105 | 107 | 107 |
Table 2
In table 2, the corresponding 101 grayscale R of 100 grayscale W, 102 grayscale G and 103 grayscale B, therefore broken the first corresponding pass
It is and forms the second corresponding relationship.
Step S16, obtain coloured race's features of skin colors RGB grayscale value, according to coloured race's features of skin colors RGB grayscale value,
First corresponding relationship and second corresponding relationship calculate the XYZ of coloured race features of skin colors RGB under the default visual angle.
It can be special by searching for coloured race's colour of skin it should be noted that obtaining coloured race's features of skin colors RGB grayscale value
RGB grayscale value mark sheet is levied to obtain, the RGB of coloured race's different zones on a picture can also be extracted using matlab
Value, takes an average value.
Step S16 is specifically included:

It is special to calculate the default visual angle coloured race colour of skin for the XYZ value of each grayscale of RGB under corresponding B grayscale value and the default visual angle
Levy the XYZ of RGB.
It is assumed that coloured race's features of skin colors RGB grayscale value is R=100, G=101, B=102, according to the first corresponding relationship
Obtain: the first W grayscale value is that the 100, the 2nd W grayscale value is 101 and third grayscale value is 102；Second corresponding relationship such as 1 institute of table
Show, the first W grayscale value is 100, corresponding R=101；Second grayscale value is 101, corresponding G=102；Third grayscale value is
102, corresponding B=106；The XYZ that each grayscale of RGB under the default visual angle is obtained in step S14, herein according to R=101, G
=102 and B=106 calculates separately out the XYZ of R, G, B under the default visual angle, by XYZ, G of the R under identical default visual angle
XYZ is added with the XYZ of B, obtains the XYZ of coloured race features of skin colors RGB under the default visual angle.
Step S17, it according to the XYZ of coloured race features of skin colors RGB under the default visual angle, calculates under the default visual angle
