已知图象4点坐标和转换后图像相对应4点坐标， 利用openCV求出homograghy 3x3 矩阵， 然后输出变换后图像,There is an input image called "warpin". The goal is to warp this image so that the tiles are approximately square, that is the camera is rotated to look down, which produces an image call

Camshitft算法，虽然opencv有Camshift函数，但是用matlab写能更好的了解原理，呵呵！-Camshitft algorithm, opencv Although there Camshift function, but with matlab can write a better understanding of the principle, huh, huh!

The normalized cross correlation (NCC) implemented in C++ and Matlab

自己完成的直方图均衡化的代码，很好用，很适合(Histogram equalization completed their own code, very easy to use)
