非平衡数据集的分类问题经常出现在许多实际应用中.支持向量机在处理这一类问题时,整体分类性能比较低.为此,Veropoulos提出的采用不同惩罚系数的改进算法可以较好的解决此类问题.此外,可以利用序列最小优化算法简单快速的解决上述优化问题.(Non-equilibrium data sets classification problems often appear in many practical applications. Support Vector Machine in dealing with this type of issue, the overall classification performance is relatively low. To this end, Veropoulos proposed punishment coefficient using different algorithms can improve the better solution such issues. In addition, can use the Sequential Minimal Optimization algorithm is simple and fast solution to the above optimization problem.)

模式分类（杜达）（第二版）电子书 及原书中的代码。绝对值得永久收藏。(Pattern Classification (Duda) (second edition) book, e-books and the original code. Definitely worth the permanent collection.)

This toolbox is meant to facilitate the manipulation of images and video in Matlab. Its purpose is to complement, not replace, Matlab s Image Processing Toolbox, and in fact it requires that the Matlab Image  Toolbox be installed.    Emphasis has  been placed on code efficiency and code reuse.

说明：  经典功率谱估计的matlab仿真。利用的是直接法(classic power spectrum estimation of Matlab simulation. The use of the direct method)

对原始图像在水平方向和垂直方向与2个滤波器(低通、高通)相卷积，可以得到4块面积为原图像1/4的子图，分别为水平方向低频和垂直方向低频(HH)、水平方向低频和垂直方向高频(HG)、水平方向高频和垂直方向低频(GH)、水平方向高频和垂直方向高频(GG)。(The original image in the horizontal direction and vertical direction and two filters (low pass, high pass) with convolution, you can get the original image area of 4 1/4 graph, respectively, horizontal and vertical direction low frequency ( HH), horizontal and vertical high-frequency low-frequency (HG), horizontal and vertical high-frequency low-frequency (GH), horizontal and vertical high-frequency high-frequency (GG).)

信号用m序列进行扩频，成型滤波和BPSK调制后经过信道发送到接收端，接收端进行解扩解调(Using m sequence spread spectrum signal, after forming filter and BPSK modulation channel is sent to the receiver, the receiver to enlarge demodulation )
