Bound box is sometimes partially formed

[salmaashraf2000]

I have used your model for detecting on my own photos but sometimes the box is not completed like in the attached photo
what can I do?
also few times hands are not recognized, what processing can I do to solve this case?
Thanks a lot for this effort

I guess this is because the rectangle annotating the hand bounding box has a line-thickness of 1. Increase it and this should not happen anymore.

The detection is not great, today I would use something like Mediapipe Hands for hand detection.
