基于harris兴趣点的图像检索程序。先特征提取，进而进行特征匹配，最后还有结果的返回。(Harris points of interest based on image retrieval process. First feature extraction, feature matching and then carried out and, finally, the results returned.)

说明：  本代码实现了K均值聚类，代码简单易懂，容易初学者学习(This code realizes K-means clustering, the code is easy to understand, easy for beginners to learn)

基于多阈值的图像分割()

图像的分水岭分割及标记分块。是进行图像处理的有利工具(Image segmentation and marking a watershed block. Is a powerful tool for image processing)

Space structure with static analysis % elastic beam element space structure with static analysis, elastic beam element

dct和混沌相结合的图像加密，速度较慢但可以用来学习(DCT and chaotic combination of image encryption, slower but can be used to study)

说明：  GVF snakes. 最近学习用到的code，可以帮助图像处理入门级的学生了解GVF snake的实现。(GVF snakes. Recent study used the code, image processing can help entry-level students to understand the realization of GVF snake.)

这个文件用PCD算法解决压缩感知（构造一个冗余字典用于图像的修复）(Using PCD algorithm to solve compressed sensing (constructing a redundant dictionary for image restoration).)

此程序实现了模糊增强实现图像的边缘检测，利用模糊方法结合边缘检测实现边缘点的提取。(Realize this procedure to enhance implementation of fuzzy image edge detection, the use of fuzzy edge detection methods achieve the extraction of edge points.)
