pca

这是数字信号处理方面的一些源码，主要涉及信号处理的基本内容，如傅立叶变换，基本的滤波器等。只供学习参考。(This is the digital signal processing some of the source, mainly involving the basic elements of signal processing, such as Fourier transform, the basic filter. Reference for learning.)

为了对目标进行快速的检测，提出了一种新的基于支持向量机的级联式分类器的构造方法。该级联分类器由若干个线性SVM弱分类器构成，结构简单，分类时间极快。针对级联结构中的每个节点的训练给出了一个新的SVM框架下的二次规划模型，这使得每个节点都有较高的正样本检测率和适当的负样本错检率。(In order to quickly detect the target, a new cascade based on support vector machine classifier constructor. The cascade is controlled by a number of weak linear SVM classifier structure, simple structure, classification of time fast. Cascade structure for the training of each node is given a new SVM quadratic programming model under the framework, which allows each node has a higher detection rate of positive samples and negative samples of appropriate fault detection rate.)

利用matlab将输入的rgb图像转化为灰度图像后，利用阈值求的二值图像，边缘算子求的边缘图像，边缘图像求归一化不变矩，Hu矩。(Matlab input rgb image to grayscale image, using the binary image threshold seeking child seeking the edge of the image, the edge operator, the edge of the image seeking normalized invariant moments, Hu moments.)

matlab信道容量，主要是解决多子信道之间的误码率和容量的仿真问题(matlab channel capacity, mainly to resolve the multi-channel bit error rate between the simulation and capacity issues)

说明：  该算法具有相对更好的稳定性和全局寻优能力，用于优化参数效果更好。(The algorithm has relatively better stability and global optimization ability, and is better used to optimize parameters.)
