We are going to create a skin detection method based on color histograms to segment skin
regions from a cluttered background, which performs skin/non-skin classification using a mixture
of Gaussians obtained from Cb and Cr color histograms. The motivation for using a mixture of
Gaussians is based on the assumption of Gaussian distribution of skin tone color and the
observation that background pixels have the same depth and outnumber the pixels in the
foreground regions
