achieving target tracking effect on video

[gjpblabla]

First of all, I was very lucky to see such excellent results, which helped me a lot. A question I would like to ask you is how to track the target of the input video based on xfeat (just like the tracking effect of the light on the ceiling you showed at the beginning), if there is such a code, it would be better. Thank you very much. I hope I haven't caused you any trouble

Hi @gjpblabla, thanks for your interest in our work!

Are you referring to an object tracker? In the demo, XFeat is used to match individual pixel-level keypoints, after which we apply a geometric transform on all matches to achieve the tracking effect based on the camera ego motion. For tracking multiple generic objects as you described, a method like OC-SORT, coupled with an object detector, may be a better fit.

Thank you very much for your reply and guidance. Is target tracking based on geometric transform only applicable to rigid objects? If I want to track a bird that flaps its wings all the time, it seems difficult to achieve
