Detailed Description

Dedicated GUI component which can be used to adjust segmentation parameters.

The RG-Chromaticity space is a special Color-Space, which can be used for a lighting-independend skin color segmentation. The segmentation is parameterized by two parabolic functions $P_1(x)$ and $P_2(x)$ . The pixel classification rule (is pixels skin-colored or not) can be defindes as follows:

bool is_pixel_skin_colored(int r,int g,int b, Parable p1, Parable p2){
   int R = (255*r)/(r+g+b+1); // "+1" to avoid a div-zero
   int G = (255*g)/(r+g+b+1);
   return p1(R) > G && p2(R) < G;
}

The so called "skin-locus" is defined by the two enclosing parables $P_1(x)$ and $P_2(x)$ . A pixel is skin colored if it is between the two parables - or more precisely: if it is on the bottom side of the first and on the top side of the second.

In addition the ChromaGUI class provides a simple RGB thresholded reference color segmenter, which can be combined with the chromaticity-space segmenter, and which can also be adjusted using GUI components.
