特征检测与匹配

图像处理中的多尺度分割程序，使用matlab开发环境(Image processing procedures for multiscale segmentation)

其中用到了 timer控件

提取糖尿病视网膜病变眼底图像上硬性渗出。将彩色图像转为灰度图，对灰度图进行形态学处理、去背景、阈值分割，最终将原图上的硬性渗出区域用绿色标记出来。(this word is to extrac the hard exudates on diabetic retinopathy fundus image. The color image to grayscale on grayscale morphological processing to the background, threshold segmentation, ultimately on the original hard exudates area marked in green.)

说明：  Matlab 实现 一维 PCA 压缩解压 图像，可以设置 eigen value 数目，观看压缩结果。(Matlab to achieve one-dimensional PCA-extracting compressed images, the number of eigen value can be set to watch the results of compression.)

一种新的基于snake模型的水平集图像分割方法：用matlab编程实现，可进行灰度图像的分割，里面有演示实例，便于学习。(A new snake model based on the level set image segmentation methods: using matlab programming implementation, can be gray-scale image segmentation, there are demonstration examples for study.)

一个求多边形面积的程序 也许会对某些人有用(Area of a polygon for the procedure may be useful to some people)

说明：  褶积模型正演模拟，非常好用，非常好用，非常好用！(Forward simulation of convolution model ,very good!)

数字音频水印的嵌入，提取，然后进行攻击性实验，检验其鲁棒性(Digital audio watermark embedding and extraction, and then attack experiment to test its robustness)

说明：  pcnn的matlab实现，pcnn神经网络主要用于图像去噪分割等(the realization of the matlab PCNN, pcnn neural network used mainly for segmentation, such as image denoising)

说明：  对多帧图像进行超分辨率处理，得到一副高分辨率的单帧度图像。(Multi-frame image super-resolution processing, get a degree of high-resolution single-frame image.)
