Object sides in feature extraction

[Leroieternel]

Hi,
I tried to extract the features by extract_feature_rgb_full.py that you provided script in issue. I noticed that there was "OBJECT_" + side+"_FEAT" key in data.lmdb, but I checked 100DOH, which is used for detecting hands and object in the paper, but they seemed not to discriminate object sides (i.e., left/right objects). Could you give some instructions about how you divide the object bounding boxes as "left" and "right"? Really appreciate your help!

Hi, thanks for your interest in our work. For the side of objects, it refers the object the corresponding hand is touching. For example, there could be left hand touch the object, but right hand not touch anything, or both hand touch the same object, ...
You could compute it using the IoU of hand-object bbox to determine the interaction object touched by left/right/both hands.

Hope it helps!
