说明：  转载的，通过眨眼前后灰度图对比是别人眼，一个学习opencv工具的好例程。(Reproduced by blinking eyes of others around the grayscale contrast, a learning tool opencv good routine.)

DCT1.m为一维离散余弦变换exp22.m为对一幅灰度图像进行离散余弦变换 exp23.m为对一幅彩色图像进行离散余弦变换(DCT1.m for the one-dimensional discrete cosine transform exp22.m for a gray image exp23.m discrete cosine transform for the color of an image discrete cosine transform)

给出了偏微分方程的径向基函数配点法的数值解法，进行了数值模拟，并且给出了图形(The numerical solution of the radial basis function with partial differential equation method, numerical simulation, and gives the graphic )

能针对二值图像进行曲线的提取. 对于背景不太复杂的图像，效果可以。 只针对单像素(extract curve from binary image only for single pixel line.)

该源程序可以实现BMP图片的压缩(BMP pictures)

哥伦比亚大学灰度拼接图像库，用于拼接图像统计特征的检测等相关研究(Studies at Columbia University gray mosaic image library for image stitching feature detection statistics)

有关改良Canny算法的一些还算可以的文献(Improved Canny algorithm on some literature.)

遥感图像分类描述，有代码，也有图像，用Matlab实现(Remote sensing image classification description, code, there are images, achieved with the Matlab)

用matlab编写的多边形画法及填充算法。(yong matlab bian xie de duo bian xing hua fa ji tian chong suan fa . )

基于梯度下降的稀疏约束 NMF 算法(NMFsc)，之前pudn上也有类似的，但缺少一个程序，这里面都包括了 (Based on gradient descent sparse constraint NMF algorithm (NMFsc), before the pudn has a similar, but the lack of a program, there are included)
