经典矩量法点匹配程序，重推导，注释说明详细(Classical point matching moment method procedure)

实现在matlab环境下的直线检测，效果很好，请大家试试。(Realize in the matlab environment linear detection, the effect of good, please try everyone.)

susan算子 基于边缘的图像分割 This function uses the SUSAN algorithm to find edges within an image(susan operator on the edge of the image segmentation This function uses the SUSAN algorithm to find edges within an image)

基于DCT的数字水印算法 通过Arnold变换对水印进行置乱，增加了水印的鲁棒性，成功的实现了水印的嵌入和提取。(Arnold transform digital watermarking algorithm based on DCT watermark scrambling to increase the robustness of the watermark, the watermark embedding and extraction. )

基于SVD的DCT域和DWT域的经典水印算法，该算法通过提取水印水印的主成分并把该主成分嵌入到奇异值矩阵，鲁邦性非常高。(the principal components of the watermark are embedded into the host image in discrete cosine transform (DCT) and for the second method, those are embedded into the host image in discrete wavelets transform (DWT). To improve the robustness, the particle swarm optimization (PSO) is used for finding the suitable scaling factors. )

说明：  计算GIF彩色图像的差异，两幅图像大小一致且调色板一致。其中Psnr 为两幅图像的psnr值.P 为两幅图像之间像素索引不同的索引值占图像大小的比例。(GIF image color difference calculation, the two images the same size and same color palette. One Psnr the two images psnr value. P index for the pixels between two images, the index values of different ratio of total image size.)

改进了的动态视频目标跟踪程序，跟踪效果很好，大家放心下载！(Improved tracking of dynamic video program, track good effect, and we rest assured downloads!)

说明：  图像增强程序，经测试有一定效果。其中采用模糊增强算法，值得参考。(Image enhancement procedures, have been tested and have a certain effect. Which the use of fuzzy enhancement algorithm, it is also useful.)

给图像加高斯白噪声,里面有详细的代码，我不知道该说些什么，只是觉得很好(gaussian noise Why must I be forced to write so many words?)
