说明：  基于MATLAB的通信系统仿真　bpsk的仿真过程就是这样的 (MATLAB-based communications system simulation BPSK Simulation of the process is)

说明：  VC调用matlab，实现VC与matlab混合编程，效果很好(VC call matlab, matlab mixed programming with VC to achieve good results,)

maybe be about usefull

Corner is important feature points in the image corners with processing information, the amount of data is relatively small, but the large amount of information. Corner has not clearly defined, research and analysis of diagonal point algorithm and comparison is necessary
