Abstract Using information of skin color to detect face region is quick and effective. However, it is very difficult to choose a suitable color space. In this paper, A novel adaptive color space YCH is proposed. It fuses the merits of the commonly used color spaces into a new simple nonlinear transformation. All the transformation coefficients can adjust automatically according to the respective characteristics of each pixel in the face image, and then eliminate effectively various unfavorable influence factors to the classifying result of the skin color and non-skin color. Experimental results demonstrate the good discriminating power of the proposed color space to all kinds of face images.
