角点检测算法是一种基于信号的点特征提取算法，Harris角点检测算子是通过Taylor级数展开法扩展了思路，计算窗口沿任何方向移动后的灰度变换情况，利用数学解析式来进一步确定特征点。-Corner detection algorithm is a point-based feature extraction algorithm signal, Harris corner detection operator is expanded by Taylor series expansion ideas

一种bss盲源信号分离的工具包 可以用于盲信号的提取 不错的(A toolkit of BSS signal blind source separation Can be used for the extraction of fanaticism, good)

利用OPENCV自带库，读取摄像头，采集信号，扣除背景，计算质心，(Use OPENCV library, read the camera, collect signals, subtract the background, calculate the centroid,)
