基于matlab的OFDM系统设计与仿真(Matlab for OFDM-based system design and simulation)

I have uploaded a code for DCT watermarking..I have embed a basic matrix into original image and calculated the difference.

this code is to diplay any wave file(heart sound) into PCG waveform

说明：  直接使用摄像头检测人脸的程序，正确率还不是很准确(Directly face the camera detection procedure, the correct rate is not very accurate)

基于肤色的人脸检测，区分出图像中的肤色和非肤色，能够运行(face detection based on face color,it can different face color from the image)

SIMPLE integer programming with pso

A Matlab toolbox to simulate light propagation for monochromatic coherent light through free-form apertures and off rough/free-form surfaces by means of a numerical approximation of the Huygens-Fresnel integral.

beam and ball simulation

说明：  计算任一语音信号的短时自相关函数，并用画图的形式表现出来，可自定义样本数，和采样频率。方便简洁。(Any calculation of short-time speech signal autocorrelation function, and use the form of drawing out the number of samples can be customized, and the sampling frequency. Easy to clean.)

matlab绘制bresenham直线，中线画直线，DDA画直线。(matlab draw bresenham line, middle drawing a straight line, DDA line drawing.)
