Data Normalization

[avisekiit]

Hi @shinseung428 ,
Thanks for this awesome repo. I just had a doubt regarding data normalization. In your hand_data.py in Line 46:
https://github.com/shinseung428/simGAN_NYU_Hand/blob/master/data/hand_data.py#L46

you seem to load images from a directory which already contains normalized synthetic data but again you normalize the synthetic depth maps in Line 76:
https://github.com/shinseung428/simGAN_NYU_Hand/blob/master/data/hand_data.py#L76

Can you please clear my doubts on the following:

1. Do you directly crop the png files of the synthetic depth maps provided in the NYU Hand Pose Dataset?
2. Do you take any special care to address the issue in the dataset that "In each depth png file the top 8 bits of depth are packed into the green channel and the lower 8 bits into blue"

Thanks,
Avisek
