What is the difference between Voxel2D_hie Voxel2D Voxel2D_sprase

[daichengqian]

i'm runing visualize_hie.py with model voxel.ckpt, it looks very well,
but when i tring test.py, Doesn't look like a match， the pretrained models maybe Voxel2D_hie
so how can i runing Voxel2D model, and what's the differenc between Voxel2D_hie Voxel2D Voxel2D_sprase
thank you

Thanks for the question. Sorry for the confusion. Voxel2D refers to the "Straight" method in Table II. Voxel2D_hie refers to the "Dense" method, and Voxel2D_sparse refers to the "Sparse-Pred" method. We provide the checkpoint for Voxel2D_hie as it has the best performance.
