There are many color space coordinate systems in color image processing, the most common is RGB space. The rest include HSV space, YCrCb space, YIQ space, and YUV space, all of which can be converted from RGB space. In most cases, the image information is stored in the RGB color system, but in the face color analysis, because the RGB color R, G, B three color components include brightness information, there is a strong correlation between, generally not suitable for skin treatment. So in general, before the skin color area is detected, the RGB color system should be converted to other color systems instead of using the RGB color space directly.
