update template during tracking #86

Closed kodonnell closed 5 years ago

kodonnell commented 5 years ago

Is there are reason why we don't update the template as we're tracking? Put another way, why tracker.init(...) is only called in the first frame in demo.py? I feel it'd get better results for tracking over long periods of time, or for slowly changing objects (e.g. people moving etc.).

Good question! However we find use moving average to update template frame or reinitialize the template frame could not improve the tracking result.

Interesting. Is that on datasets with deformable objects over long periods (e.g. people walking)? Moving average is also a clever idea. I'd be interested to see the code added if you already have it and it's easy.
