背景差分法，帧间差分法,可以有效基于视频序列检测出动态目标，实现有效检测-Inter frame difference and background difference moving target detection phase fusion under the opencv platform based on vc++6.0

该程序可以实现两个键相信号之间相位差的计算，准确度高-The program can achieve the calculation of the phase difference between two key phase signals, with high accuracy
