How could I use optical flow to estimate proposal motion?
Hi, sorry to bother you again. I'm commited to solving the existing problems in OWT proposed by your paper. As mentioned in your paper, the baseline uses both optical flow and re-id similarity scoring and combines these into final tracks using tracklet merging. But I can't find the code to generate proposals' motion with optical flow. Looking forward to your reply. Thank you!
Calculating optical flow between frames is a separate process, so I did not include that into this repo. The optical flow we used is generated by PWC-Net. Use that to reproduce our result.
But of course you can use other Optical-Flow-Nets which have "better" performance. E.g. RAFT is something you probably wan to explore.
