5相位编组法实现纹理直线边缘的检测程序代码(代码以子函数形式给出) function gradephase(x)

基于相位角点检测的特征匹配研究，很好用的。-Corner detection based on phase matching of the characteristics of research, a good use.

可以得到很精确的幅值、频率、相位估计，用于信号特征提取、信号消噪，有循环检测，周期性检测。- You can get a very accurate amplitude, frequency, phase estimation, For feature extraction, signal de-noising, There are cycle detection, periodic testing.
