小波变换的相关matlab代码，实验中均附有所需图片，直接运行可以显示(wavelet transformation)

深度优先搜索算法Matlab源码 ％ 此程序从国外网站收集得到，是标准的深度优先搜索算法，可实现节点遍历和检测回路的功能，详细情况请看原英文注释 ％ 我在此程序中添加了随机性，即遇到分叉时，随机选下一个节点，成为随机深度优先搜索算法(Depth-first search algorithm Matlab source this procedure site collected from abroad, is the standard depth-first search algorithm, can be achieved and the detection circuit node traversal functions, details see the original English Notes I added this procedure randomness, that is, bifurcation encountered when a randomly selected node, become a random depth-first search algorithm)

The program deals with mixture models which gives the combinational output of the given input to the system

说明：  此包主要对班级管理，对班级的很多内容进行详细的管理(classmanage)

说明：  这是“Active contours driven by local and global intensity fitting energy with application to brain MR image segmentation”（简称LGIF模型）的MATLAB源代码。LGIF模型是非常重要局部区域活动轮廓模型, 它结合了CV模型和LBF模型各自的优点。(This is the "Active contours driven by local and global intensity fitting energy with application to brain MR image segmentation" (referred to as LGIF model) of the MATLAB source code. LGIF model is very important to local area active contour model, which combines the CV model and the merits of LBF model.)
