How to compute heights Z in voxel space? #21

Excuse me, I didn't understand the core of following table in your paper. image

Could you please explain how to compute heights Z in voxel space, such as h=5 or h=11. Looking forward to your early reply. Thanks a lot!

Hi, the height here indicates number of the sampling points in voxel space construction. For example, the Z of image voxel space in Figure 3 of the main paper is set to 5 if we use h=5.
