中文说明：这段代码实现了著名的Chan-Vese分割算法，该算法来自于论文“无边缘活动轮廓”。这项技术使初始曲线变形，以便根据两个区域的平均值将前景与背景分开。该技术对初始化非常鲁棒，并且在前景和背景有差异时会给出非常好的结果意思是，这个代码在实现中使用活动轮廓和级别集。它还可以作为实现各种基于区域的活动轮廓能量的良好框架。1.）下载2.）解压缩3.）运行>；>；区域
English Description：
This code implements the well-known Chan-Vese segmentation algorithm from the paper "Active Contours Without Edges." This technique deforms an initial curve so that it separates foreground from background based on the means of the two regions. The technique is very robust to initialization and gives very nice results when there is a difference between the foreground and background means.This code uses active contours and level sets in the implementation. It could also serve as a good framework for implementing all kinds of region-based active contour energies.1.) Download 2.) Unzip 3.) Run >>region_s
