How to obtain voxel labels?

[Haerxu]

Hi,

Thanks for releasing code! I have a question about how to obtain voxel labels? In the code, you only compute voxel coordinates and features. How to obtain voxel labels?

Voxel label is not computed. In fact, we convert the voxel output prediction to point-level prediction then compute the loss.

SoftGroup/softgroup/model/softgroup.py

Line 374 in 11dcbfd

output_feats = output_feats[input_map.long()]

Hi,

In the voxelization code softgroup/ops/src/voxelize/voxelize.cpp, there are 5 choices of voxelization and 4 is chosen in the code. Do you know other meaning of the voxxelization? I want to use the voxel labels, but I don't think mode=4 can output voxel label becuas it use average pooling within each voxel.

mode 0=guaranteed unique 1=last item(overwrite) 2=first item(keep) 3=sum, 4=mean
