ToPercentCoords

[EddieEduardo]

Why do I think there is a tiny inaccurate place in Fuction ToPercentCoords in utils/augmentations.py in line 85-96 ?

It feels like the following lines
"""
boxes_pre[:, 0] /= width
boxes_pre[:, 2] /= width
boxes_pre[:, 1] /= height
boxes_pre[:, 3] /= height
boxes_next[:, 0] /= width
boxes_next[:, 2] /= width
boxes_next[:, 1] /= height
boxes_next[:, 3] /= height
"""
should be corrected as:
"""
boxes_pre[:, 0] /= width-1
boxes_pre[:, 2] /= width-1
boxes_pre[:, 1] /= height-1
boxes_pre[:, 3] /= height-1
boxes_next[:, 0] /= width-1
boxes_next[:, 2] /= width-1
boxes_next[:, 1] /= height-1
boxes_next[:, 3] /= height-1
"""
cause when I used the original codes as an example to extract a specific number in a tensor by means of function torch.nn.functional.grid_sample, it wouldn't get the expected number, but when I changed width/height to width-1/height-1 , it came out the expected number.
Does anyone have the same confusion?
