% 饱和度计算（对比HSV_S看不出区别）
% 最大值为0时，000全黑的点饱和度为0
% RGB_MAX = RGB_MIN 时， 饱和度为0
RGB_MIN = min(min(RGB_R, RGB_G) , RGB_B);
RGB_MAX = max(max(RGB_R, RGB_G) , RGB_B);
RGB_MAX_NO_ZERO = RGB_MAX;
RGB_MAX_NO_ZERO(RGB_MAX_NO_ZERO == 0) = 1;
Saturate = double(RGB_MAX - RGB_MIN) ./ double(RGB_MAX_NO_ZERO) ;
% 可以对比HSV_S和Saturate
