semi-supervised learning 半监督局部线性嵌入(semi-supervised learning )

说明：  代码很好的实现了基于a-star的最短路径寻找算法，并可以对寻找的路径有一个限制(Code is a good realization of a-star-based shortest path search algorithms, and can find the path there is a limit)

非局部平均，用来去除灰度图里面的噪声，效果明显(Probability Non-Local Means)

这是SPAMS的原始代码，是稀疏表示的重要工具箱~(This is SPAMS original code, is an important toolbox sparse representation)

显示BMP图片，并绘制直方图。程序无误，可运行。(Display BMP image, and draw the histogram. Program is correct, you can run.)

基于整数小波变换的图像可逆水印，很好用，可逆性很强，自己查找的资料(Image reversible watermarking based on integer wavelet transform is very useful. It has strong reversibility and finds information by itself.)

中值滤波，取出奇数个数据进行排序，用排序后的中值取代要处理的数据即可(median filtering.rar)

图像亮度和对比度调节，已验证，分别有亮度调节和对比度调节的调整框(Image brightness and contrast adjustment, has been verified, respectively, brightness adjustment and contrast ad)

2012 CVPR 文章：Segmentation Using Superpixels A Bipartite Graph Partitioning Approach对应的代码(2012 CVPR paper：Segmentation Using Superpixels A Bipartite Graph Partitioning Approach)

水平集方法及其在图像分割中的应用研究。09年中科大的博士论文，很详细的讲解了水平集在图像分割中的应用(Level set method and its application in image segmentation study. Cultivation of doctoral thesis in 2009, a very detailed explanation of the level set image segmentation in)
