在复杂背景下双椭圆模型结合在CbCr和CgCr平面内体现的肤色聚集性和集中性的检测效果要比单高斯模型的效果好。在YCbCr和YCgCr颜色空间中，虽然Y分量和Cb、Cr、Cg分量表示的性质看似是相互独立的，但它们都是建立在红、绿、蓝三个基本颜色分量值的基础上算出来，因此它们之间仍然存在着千丝万缕的关系。根据肤色在两种色彩空间中体现出的聚集性提出CbCr-CgCr双椭圆肤色模型-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
