说明：  功能:在彩色图片上令肤色区域为白色,其余为黑色,并用矩形将各连通区域标志出来,用matlab实现(Function: to make color in the color picture on the white area, the rest is black, and will each connected region with a rectangular logo out to achieve with matlab)

This problem is main to solve a PDE. And we have validate hte program with the analysis results.
