svd图像压缩，程序中使用了三种方法的SVD，包括直接svd，分块svd和小波svd(3 svd comprecessions.)

用Matlab的GUI界面设计的图像分割演示，包括阀值法、边缘检测法、区域法(Demonstrates the Matlab GUI interface design, image segmentation, including the threshold method, edge detection method, regional law)

中值滤波是一种非线性数字滤波器技术，经常用于去除图像或者其它信号中的噪声

傅里叶梅林变换实现图像配准，对旋转，缩放，剪切，平移都有效(Fourier Mellin Transform for image registration, valid for rotation, scaling, cropping, shifting)

指纹图像处理，细化，锐化，二值化，特征点的提取。(Fingerprint image processing, refining, sharpening, binarization, feature point extraction.)

说明：  生成混沌随机序列并实现对彩色图像的加密，(Encryption of color image)

matlab 写的提取图像亚像素边界的程序，和Canny算子有比较，里面有两张示例图像！(matlab write the image to extract sub-pixel border procedures, and the Canny operator have more, there are two examples of images!)

SIFT算法，可以有效的找到不同画面中的对应特征点，在跟踪和图形识别方面有很好的用途(SIFT algorithm, can effectively find a different screen the corresponding feature points, in the tracking and pattern recognition as a very good use of)

说明：  opencv中的一段 snake的代码, opencv snake,(A piece of Snake code in opencv, opencv snake,)

一些dwt数字水印 源码和一些资料希望对大家有用 呵呵(dwt digital watermarking)
