Constant aspect ratio #92

Closed Ali-Parsa closed 3 years ago

Hi Why did you consider the aspect ration constant in your paper and implementation?

abewley commented 4 years ago

This choice was made to keep the state-model simple. Since people/pedestrians where the main object class for tracking in the motchallenge the aspect ratio can be approximated with a constant.

Naturally, this isn't true 100% of the time. I.e. someone may transition from standing to lying or the camera's pose may change or a long truck is turning. If this situation is common to your use-case, you should probably consider extending the estimation model to suit.
