Description:
A novel approach for skin segmentation and facial feature extraction is proposed
The proposed skin segmentation is a method for integrating the chrominance components of

nonlinear YC C color model The chrominance components of nonlinear YC C color space

are modeled using a subgaussian probability density function and then the face skin is seg
