Visible meaning in RHD #32

Closed nitba closed 4 years ago

nitba commented 5 years ago

Hi @zimmerm ,

in RHD dataset what does visible mean? does it mean to be occluded or not Or does it mean the existence of hand (joint) in image?

Visible is determined based on a heuristic that evaluates the number of hand segmentation pixels in a neighborhood around the projected keypoint. So it should evaluate to false if the point is outside the image frame or the neighborhood is occupied by a segmentation class that is not related to the keypoint in question.
