Confusion about the nms implementation

[chinmay5]

I have some doubts regarding the nms implementation. Specifically, the part inds + 1 being used here:-

fast-rcnn/lib/utils/nms.py

Line 35 in b612190

order = order[inds + 1]

The remaining code is quite clear but I am not able to wrap my brain around this particular line

you can see xx1 = np.maximum(x1[i], x1[order[1:]]) , x1[order[1:]] is start from 0, so all the indices in xx1 wiil decrease 1. and order is complete (include i).
