Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer (an eye or a camera) and the scene.[2][3] The concept of optical flow was first studied in the 1940s and ultimately published by American psychologist James J. Gibson[4] as part of his theory of affordance. Optical flow techniques such as motion detection, object segmentation, time-to-collision and focus of expansion calculations, motion compensated encoding, and stereo disparity measurement utilize this motion of the objects surfaces and edges.[5][6]

说明：  自相关函数和互相关函数的matlab计算和作图，这个是信号分析里的概念，他们分别表示的是两个时间序列之间和同一个时间序列在任意两个不同时刻的取值之间的相关程度。(Self correlation function and cross-correlation function of matlab calculation and drawing, this is a concept in signal analysis, they are respectively represent the is between any two different time value relevance of the two time series and the same time series.)

特别好用的二值化程序 比matlab自带的好 因为是分区域二值化 不需要事先设定阈值 而是自动计算阈值，对您的实验会有帮助的(very useful)
