基于opencv，对视频文件进行灰度、轮廓检测后用自编的简易播放器播放出来。-Based opencv, gray video files, post-test with a self profile player to play out simple.

图像处理的各种基础变化，包括频域，时域的，适合基础自学。包括测试的图像。-A variety of image processing base changes, including the frequency domain, time domain, for the basis of self-study. Including images of the test.

本代码实现基于Retinex理论的三种方法，分别为单尺度Retinex，多尺度Retinex，以及自商图像方法。直接运行每个文件夹下的test文件就可以得到对应的方法的处理结果。-This code implements three methods based on Retinex theory, respectively, for the single-scale Retinex, the multiscale Retinex, as well as self-quotient image m

基于matlab编程的，将箭头修改颜色，修改大小，自测可用，我们画完箭头后，可以添加颜色，使图形看起来更加的丰富-Arrow modify the color, change the size, self-test available
