Changing threshold does not help to reduce false positive

[edwardnguyen1705]

Hi, thank you for sharing excellent project. I have been trying to change to the threshold (even to 0.95) to eliminate false detection, but it does not help.

hand_tracking/hand_tracker.py

Line 125 in bc316be

detecion_mask = self._sigm(out_clf) > 0.7

Do you have any suggestion?
