用matlab实现了视频的分割，能够读取视频的每一帧，比较相邻两帧的相似度，下把图像分块，比较每一块的相似度-Matlab achieved by video segmentation, can read each video frame, comparing the similarity of two adjacent, under the sub-image blocks, each of the similarity comparison

本程序采用半隐式方案实现变分水平集图像分割方法中的 “C-V”模型(Active contour without edge) -Iris Recognition based on Active Contours
