Question about annotation

[ChuanxinSong]

Hi, thanks a lot for your contribution.
However, I'm having some problems with the annotation of the dataset you made.
I noticed that the format of visible_bbox in "uoais_train_tabletop.json file" seems to be "[x_min, y_min, x_max, y_max]", like "[346, 225, 393, 253]". But in ". /sample_data/annotation_final.json" file the format of the bbox is "[x_min, y_min, width, height]", e.g. "[355, 153, 131, 84]".

But when I try to change the format of visible_bbox in "uoais_train_tabletop.json" to "[x_min, y_min, width, height]" for evaluation, the accuracy is very low.
So, I would like to enquire if my understanding of the above annotation is correct?

Hi @ChuanxinSong, all annotations for visible_bbox in uoais_train_tabletop.json and . /sample_data/annotation_final.json are in [x_min, y_min, width, height] format.
This explains the poor evaluation performance when you did an extra conversion of the visible_bbox annotations that were already in [x_min, y_min, width, height] format.
