对图像分块,计算每个块的均值和方差,并给出了结果的图象化表示,易于观察(Image sub-blocks, each block calculated the mean and variance, and gives the results of the image that is easy to observe)

能够实现图像的纹理检测，可以直接调入一个图像然后得到纹理(to achieve the texture image detection, can be directly transferred to a texture image is then)

zhou wang提出的结构相似性图像质量评价算法，是一种全参考的质量评价模式(zhou we analyze the dynamic process of the structural similarity of image quality evaluation algorithm, is a reference to the quality of the whole evaluation model)

根据冈萨雷斯数字图像处理中做的，使用matlab进行直方图的均衡化以及直方图匹配程序，附带原图像(According to Gonzalez, digital image processing to do, the use of matlab to histogram equalization and histogram matching program, with the original image)

这是一个基于matlab语言编写的沃尔什变换程序，里面有一个4X4的矩阵可当例子，修改相关参数可用于2^n的矩阵(Walsh Transform matlab language based program, which has a 4X4 matrix when the example 2 ^ n matrix can be used to modify the relevant parameters)

产生螺旋波面的m文件，拓扑核数是3,相位改变量和高度可以自己调节。内附平面波和球面波的示意图以及产生的图片(generating helical wavefront whose topological number is three)

超像素分割程序，既有原码，也有可执行程序，验证过，好用。(Super-pixel segmentation procedure, both the original code, there are executable programs, proven, easy to use.)

三维点云配准kd-tree搜索算法，用于特征点的搜索匹配(3 d point cloud registration kd- tree search algorithm, is used to search of feature point matching)

一种基于景深的去雾方法，将按通道中的最大值和最小值作为景深基准线，计算其垂直方向上的暗通道像素均值作为透射图，实现去雾，对航拍图效果显著(A dehaze method based on the depth of field, draw a depth datum line according to the maximum value and minimum value of the dark channel, calculate the pixel of the dark channel at the line perpendicular to the depth datum line.Then the transmission map has been gotten. This method performs good especially when processing the aerial map.)

利用fastICA算法实现了两幅图像的分离。内附源图像文件（两种）。同时还利用峰值信噪比PSNR和性能指标PI实现了对分离效果的评价。原创代码。(fastICA algorithm is uesd in seperating the mixed images.)
