该文件夹包括基于邻阈的小波图像去噪程序。主程序为wave_neighbor.m，实现3*3和5*5邻域去噪；wov_win.m为函数m文件，实现3*3和5*5的滑动窗口；cacupsnr.m为函数m文件，计算mse和psnr等。(This is about image denoising with the method of wavelet.It includes 3×3 and 5×5 neighborhood window.)

一个基于DFT的水印算法源码；其中有嵌入，提取，测试图片；还有攻击程序，可以用来测试(DFT-based Watermarking Algorithm source including embedding, extraction, testing picture there are attacks on the procedures that can be used to test)

常见的工程光学的现象模拟，如平面波球面波的模拟，一些干涉现象的仿真。(Common phenomenon of optical simulation projects, such as plane wave spherical wave of the simulation, the simulation of some interference.)

opencv,图像处理，关于物体粘连问题的检测，基于凹性分析的分割方法(opencv, image processing, object sticking problem on detection, segmentation method based on analysis of the recess)

CVPR2013中出现的一种显著性特征检测算法，该算法用于模拟人眼视觉识别过程，提取图像中的显著性特征借后期目标对象的检测跟踪等使用，该算法(Context-Aware Saliency Detection。matlab implementation of an classical saliency detection alrogithm,which imitate our recognition process of eyes)

实现了Chan－Vese算法，参考文献active contour without edges, 图像处理方面引用率最高的文献之一(Realize the Chan-Vese algorithm, reference active contour without edges, image processing, to quote one of the highest rates of the literature)

yuv420 to_yuv420p 程序(yuv420 to_yuv420p )

说明：  基于块分割的图像拼接，将图像按块拼接，缺点是速度很慢，算法有待改善(Block-based segmentation of the image mosaic, mosaic images by block, the disadvantage is very slow, the algorithm needs to be improved)

Graphics PresentationsMandelbrot Set Function,

基于最大流最小割定理的图像分割,里面有一个例子，(Image segmentation based on maximum flow minimum cut theorem)
