说明：  自己写的一个基于肤色模型的人脸检测的matlab代码。( I write a face detection based on skin color model with matlab.)

this is the code for canny edge detection of image using matlab.

可以利用此书来编辑抗震问题的解决过程中利用matlab来实现(this is helpful to solve some problem which comes to anti-sesimic)

说明：  这个程序简单的介绍了OFDM的变体f-ofdm的误码率(This program simply introduces the bit error rate of the variant f-ofdm of OFDM.)

说明：  使用matlab实现贝叶斯向量自回归模型，可用于经济学中的预测(It can realize Bayesian vector autoregressive model, and it can be used to predict in economics.)

这是根据点拟合圆和直线的matlab程序，比较简单实用(This is the basis of points won and a straight line fitting the matlab procedure is relatively simple and practical)

超宽带信号中高斯脉冲和冲击脉冲的产生，以及脉冲位置调制（PPM)和脉冲幅度调制(PAM)，形成一个完整的电路来完成整个过程(UWB signal in the Gaussian pulse and impulse generation, and pulse position modulation (PPM) and pulse amplitude modulation (PAM), to form a complete circuit to complete the whole process)

关于简单的凝视成像的程序，自己编写，希望交流！(Staring imaging procedures, written in the hope that the exchange)

说明：  衰减曲线法实现PID参数整定 给出系统前向通道的传递函数，matlab计算PID参数(PID parameter tuning by attenuation curve method)

提取脉搏波后，通过此小波变换的处理，达到去除基线的目的(After the pulse wave extracted by wavelet transform of this treatment, to remove the purpose of the baseline)
