nms.py - why are we incrementing inds of order?

[euwern]

Hi can someone tell me why is the inds of order in line 35 of nms.py get incremented? Wouldn't that mess up the inds? If I understand the code correctly, the inds refer to all boxes that is smaller than the specified overlap threshold of the current selected box.

I did take a look at the matlab implementation of nms. The indices wasn't incremented in the code.
