说明：  用L-M 优化算法与贝叶斯正则化算法训练同一个样本(By LM optimization algorithm with Bayesian regularization algorithm for training with a sample)

本段Matlab是运动员心跳信号检测项目一个心跳信号出噪仿真程序，文件给出了心跳信号的样本，是一完整的数字信号处理应用程序。(This paragraph is an athlete heartbeat detection Matlab project a heartbeat out noise simulation program, document gives a sample of the heartbeat is a complete digital signal processing applications.)

MATLAB code for LC2 Similarity Measure. The main.m file provides a working example with test images.

利用matlab处理图像，分别用高斯滤波，均值滤波和中值滤波，对同一个噪声图像处理及得到结果(Using matlab image processing, respectively, with a Gaussian filter, mean filter and median filter, image processing on the same noise and get results)

特征降维方法，其中包含有典型的特征组合方式——PCA和特征选择中的SFFS，SBS，SFS。共四类常用的特征降维方式。(different features dimensionality reduction methods.)

波束形成过程中，滤波器权值固定不变。一旦阵列的几何形状、目标方向确定，其波束模式特性也将确定(In the beamforming process, the filter weights are fixed. Once the array geometry and target direction are determined, the beam pattern characteristics will also be determined.)

说明：  麦克风阵列形成的波束beampattern图形，可调整麦克间距和信号带宽来得到需要的波束图(microphone array beam forming the beampattern graphics, Mike adjustable spacing and the signal bandwidth they need to beam map)
