/**
    \section Overview
    The skin class provides access to a skin color segmentation algorithm.
    Therefor the class provide a training procedure and a skin detection algorithm.
    In a first step the skin parabola parameter have to be trained or if the parameter set 
    is allready known the can be set directly. After this the detection algorithm is well 
    prepared for detection the skin color.
