Why the ground truth is the absolute coordinates instead of the ratios #1060

Hi,

I am really new to YOLO. However, as I am looking at the XML file, I found that the ground truth of the bounding boxes are the absolute coordinates for each boxes. However, as I read the paper, should not the ground truth to be {bx,by,bw,bh}, and bx by represent the aspect ratio of where the object is with respect to its located grid cell, which is bounded between 0~1 ?

I am asking this because I want to create my own dataset, and at this point, I do not know how I should annotate my ground truth of each the bbox's coordinate.

Thanks for helping me,

Regards.
