核pca(kernel pca)教程，核可以用其他的核代替

基于小波变换的数字音频水印算法 水印嵌入源程序 (With the rapid growth of computers, network and multimedia technologies, powerful and low cost computers allow people to easily create and copy digital products of multimedia. The Internet has made it easy to distribute the information at very low cost. However, these technologies also can be illegally copied, modified and redistributed multimedia data without regarding for intellectual property rights ownership. )

SIFT特征点检测，配准、匹配，代码经验证可用(sift match ransac appendimages)

大家好，我已经给光网络的代码基础中的蜜蜂蚁群算法的路由算法。欢迎大家下载、试用。谢谢大家的支持！

重叠保留法求两序列线性卷积，是针对循环卷积代替线性卷积算法中由于时间不足造成的算法太大的缺陷(Overlapping seeking linear convolution of two sequences is a place for the circular convolution linear convolution algorithm, the algorithm because of the time caused much less defects)

this is the code to do spectrum analysis using FFT.
