求解两幅压缩前后图片A和B之间的峰值信噪比(To find the PSNR (peak signal-to-noise ratio) between two intensity images A and B, each having values in the interval[0,1]. The answer is in decibels (dB).)

All of MATLAB toolbox links,can download them from internet.best gift for newbies!!

经验模态分解（EMD）方法（平稳化过程）是一种全新的处理非平稳数据序列的方法，其基本思想是：假如一个原始数据序列X(t)的极大值或极小值数目比上跨零点（或下跨零点）的数目多两个（或两个以上），则该数据序列就要进行平稳化处理(Empirical Mode Decomposition (EMD) method (a smooth process) is a new deal with non-stationary data sequence method, the basic idea is: If a raw data sequence X (t) the maximum or minimum number of than the cross-zero (or under the cross-zero) number more than two (or more), then the data is necessary to carry out a smooth sequence of treatment)

说明：  一个matlab的工具包,里面包括一些分类器 例如 KNN KMEAN SVM NETLAB 等等有很多.(a Matlab tool kits, including some inside classifier for example KNN KMEAN SVM NETLAB etc. plenty.)
