matlab编程时常见错误,如果越到问题，可以很好地帮助你解决出现的问题。(This book tell you how to deal with mistakes about the matlab programming)

说明：  基于干涉极值法提取相位功能函数，可以快速提取干涉条纹的相位(The phase function is extracted based on the interference extremum method, which can quickly extract the phase of interference fringes)

tracker.m Continuously keeps taking snap in real time and sending to function isub for tracking isub.m It is a function which takes two consequent frames, subtracts them(background gets subtracted), converts the resulting image into binary, finds the centroid of largest area of connected pixels and marks it(tracks it) The code has been tested in MATLAB 7.6
