The content of this paper is the proposal of two techniques for the modeling of skin color in images using a combination of spaces of colors HSV with YCbCr and HSV with CIELab. To determine the intervals of pixels nonskin color uses the components H and S, on the other hand, the intervals of pixels skin color uses the components Cb, Cr, a and b. There are compared the results of the technique HS-CbCr which is the combination of the components H and S (pixels non-skin color) with the components Cb and Cr (pixels skin color), against the technique HS-ab that of the same form is the combination of H and S but with the components a and b (pixels skin color). It analyzes the efficiency of each technique for the segmentation of skin based on the percentage of detection of skin and non-skin. The experimental results showed that technique HS-ab is better than the technique HS-CbCr because of the precision in addition the obstacles of luminance are discarded because in both techniques the luminance component is eliminated.
