imdb flipping image boxes has a typo?

[Ahmed-M-Naguib]

Hi, i'm trying to train the net on my own data and classes.

i'm getting assertion error in imdb.py line 120

the lines are:

boxes = self.roidb[i]['boxes'].copy() oldx1 = boxes[:, 0].copy() oldx2 = boxes[:, 2].copy() boxes[:, 0] = widths[i] - oldx2 - 1 boxes[:, 2] = widths[i] - oldx1 - 1 assert (boxes[:, 2] >= boxes[:, 0]).all()

i'm not sure. if the purpose is to flip image boxes, shouldn't it be like: boxes[:, 0] = widths[i] - oldx1 - 1 boxes[:, 2] = widths[i] - oldx2 - 1

since boxes[0] is x1, and boxes[2] is x2?

UPDATE: sorry, i just though about it. nevermind!
