语音信号处理程序

对DOA进行估计的一种较好的方法，能精确地对参数进行估计(Of the DOA estimate of a better way to accurately estimate the parameters)

QuantRefine using matlab

Truss optimization using genetic alorithm in matlab under evolutionary computing.

说明：  AR滤波器滤除信号中的低频分量信号,实现降噪的目的(The AR filter filters out low-frequency component signals in the signal to achieve noise reduction.)

一个Active Form的范例(an example of the Active Form)

合成孔径雷达(SAR)的点目标仿真(附件带代码程序)，适合初学者入门用，并解释了每一个语句的作用(Synthetic Aperture Radar (SAR) of the point target emulation (annex with code programs), a detailed description of the program and describes the role of the end of each program)

提取出RGB图片中的ROI区域，取得的ROI区域同样是RGB。示例图片为人体伤口图。大小为599*800*3，其中包含皮肤和伤口，伤口为ROI，本代码可以提取出伤口区域，得到的结果是原图像皮肤部分变为黑色，伤口区域依然为原图。

PSO与GA混合优化算法，可实现比单纯使用PSO或者GA算法更好的优化效果(PSO and GA hybrid optimization algorithm, can achieve more than a simple algorithm using PSO or GA optimization results better)

本代码是利用dwt小波分析，实现了对音频加入灰度水印的源代码，可直接运行，生成两个音乐文件，一个是嵌入声音后的，另外一个是噪声文件。(This code is the use of wavelet analysis dwt, the realization of audio into grayscale watermark source code can be run directly, generates two music files, one after the embedded voice, the other is the noise file.)
