Questions about the code

[qsisi]

Hello! I got several questions about the code:

1. https://github.com/POSTECH-CVLab/DHVR/blob/83cede6ed2953a8be794d59abcd2a4d943659a21/src/dhvr.py#L113-L114 When projecting from the 6D tensor space back to the axis-angle and the translation space, why add a 0.5 bin shift on the tensor space?
2. https://github.com/POSTECH-CVLab/DHVR/blob/83cede6ed2953a8be794d59abcd2a4d943659a21/src/dhvr.py#L52-L55 During triplets sampling, why filter out those triplets with close spatial distances (< 1.5 voxel_size)? Is it related to the training performance?

Thanks for your reply.
