Ball labels not accurate

[amartig]

Hi, I have been checking the ball ground truth bounding boxes and they seem to not be accurate at all when the ball is moving. Is that accounted for? Even in your tutorial video of the tracking challenge (https://www.youtube.com/watch?v=nxywN6X_0oE&t=406s) (min 8:24) the ground truth you show is very inaccurate.

Hi @amartig, the bounding boxes are labeled on keyframes and interpolated for other frames. So your observation is correct that when the ball or people are moving very fast, the bounding boxes more inaccurate.

Is there an indication as to which ones are the keyframes and which ones are the interpolated ones?
