Pattern-Recognition

程序用matlab实现基于模板和肤色的人脸检测,首先利用肤色信息检测出可能的人脸区域,然后进行模板匹配.可以实现一幅图片中多人脸的检测.(procedures using Matlab based templates and color of face detection, the first to use color information may detect a face, then template matching. can be achieved over a picture of face detection.)

This MATLAB Code plot the aperture efficiency Vs the subtended angle. The user determine the value of n and the code plot and tell what is the angle value that achieves max efficeiency and the value of this efficiency.

目前我见过分析最为全面的2PSK系统的基于MATLAB的仿真分析M文件(At present I have seen of the most comprehensive 2PSK system simulation analysis based on MATLAB M file)

计算光纤陀螺的非线性度，并且绘制出不同速率对应的非线性度曲线。(Calculation of the non-linearity of the optical fiber gyro, and draw out the different rates corresponding to the non-linearity curve.)
