There are many available optical flow algorithm implementations online now. To choose which algorithms the best for you is your experimental efforts. In this repo, I will summarize some good implementations right now.
- mex_OF implemented from Brox ECCV2004 is not fast enough, but the results are good.
- Opencv implemented Brox ECCV2004 is fast, but not accurate engough. There might be a bug with Opencv implementation.
- Opencv implemented TVL1 is the best so far with balance between efficiency and accuracy.
