Hi @mizeller, yes, the current online model indeed only works with 4-frame windows. There is going to be a lag of 3 frames, and we don't have a solution for this yet.

Thanks! Fixed it: fac2798

@nikitakaraevv Thank you for the speedy reply! I guess I'll continue with the regular CoTrackerPredictor if there is no easy "hacky" solution in that case :-)

(BTW: the variables W and H are not initialised in the case of is_first_step=True
and queries is not None
in the online predictor --> small bug)
if is_first_step:
self.model.init_video_online_processing()
if queries is not None:
B, N, D = queries.shape
assert D == 3
queries = queries.clone()
queries[:, :, 1:] *= queries.new_tensor(
[
(self.interp_shape[1] - 1) / (W - 1), # here
(self.interp_shape[0] - 1) / (H - 1), # and here
....
