Will centertrack work if the test video is long?

[HAOCHENYE]

I found that centertrack use the pre_hm from the ground truth during training process. However, centertrack predicts the bbox and id using pre_hm calculated by previous frame. Actually, this pre_hm is not accurate. I wonder that will centertrack work when the video is long since the pre_hm is not accurate during test process and the error will accumulate.

That's a valid concern. We didn't observe it in our current use, probably thanks to we have simulated false positives on the input heatmap in training. If the concern becomes more critical in your application, you can probably increase the simulating false-positive ratio in your training.

why not use the pre_hm from the prediction?

@qiuhaining have you understood why not use the pre_hm from the prediction? I have the same confusion.
