pyflow optical flow
dense optical flow alogirhtm 중 성능이 좋은 classical한 algorithm을 발견했다.
아래 git으로, Ce Liu's C++ implementation of Coarse2Fine Optical Flow 를 python wrapper를 만든 것이다.

windows에서 build시 아래 부분 수정해줘야 한다.
* src 폴더의 project.h에서 #define _LINUX_MAC 을 주석처리 해야 한다.
// if the files are compiled in linux or mac os then uncomment the following line, otherwise comment it if you compile using visual studio in windows
// #define _LINUX_MAC
// #define _OPENCV
