Good background in complex dual oval model incorporated within CbCr and CgCr plane reflect complexion aggregation and concentration detection results than the single Gaussian model results. And YCgCr in YCbCr color space, although the nature of the Y component and Cb, Cr, Cg component represented appears to be independent of each other, but they are all based on red, green, blue three basic colors based component values get on out Therefore there are still intricate relationship between them. Proposed CbCr-CgCr double ellipse skin model according to reflect the color in both color space clustering
