边缘轮廓跟踪后傅立叶算子特征。这是课上的一个作业，原图->阈值分割->canny轮廓算法->边界表示->边界傅立叶算子描述->结果-After tracking the edge of the outline of the characteristics of Fourier operator. This is a class operation, image->threshold->canny contour algorithm->boundar

主动轮廓跟踪的matlab GUI显示，对于学习GUI很有帮助。-Active contour tracking matlab GUI display, helpful for learning GUI.
