Hi , in the vbb2voc.py :
Q1) why E.difficult(0) are for all objects zero ? i want to have difficult of objects.
Q2) what are these ?lock, posv

commented

@zeynali In my case, I just wanna use all instances so I set all difficult to 0. In Caltech pedestrian dataset, difficult is not directly provided. Maybe you could use occlude as reference of difficult.

As for lock and posv, the former is to indicate if bounding box is locked during labeling; the latter is to indicate the bounding box of visible region.
