指定图像部分，进行图片裁剪或者放单，类似于电商网站的图片放大镜(Specify the image part, cut or put out the picture, similar to the electricity supplier website picture magnifier)

图像压缩标准jpeg的源码。使用的语言为C语言。(Image compression standard JPEG source. The language used for the C language.)

matlab输入两幅图像，最直接简单地计算图像psnr，高手者请跳过(matlab input two images, the most straightforward to calculate the image psnr, you are invited to skip)

meanshift算法的python实现 + 图像化显示(meanshift with python)

伯克利图像小组提出来的图像分割评价指标：边界误差。(Evaluation of image segmentation. Image: Berkeley group boundary error.)

考虑混沌效应的粒子群算法，比常规粒子群更容易跳出局部解(optimization method of PSO, concerning the Chaos effect.)

包括基于SIFTGPU的sift特征提取，sift匹配，基于ransac误匹配点剔除等(SIFTGPU based sift feature extraction, sift matching, mismatching points based ransac removed, etc.)

说明：  这是冈萨雷斯经典教材数字图像处理（MATLAB版）的所有源代码，很辛苦才获得的(This is a classic textbook Gonzalez Digital Image Processing (MATLAB version) all the source code, it is hard before they are allowed to)

说明：  super resolution可实现 很多算法(a lot of super resolution algorithms can be realized)
