Specifically, we adopt a bottom-up strategy and group the input voxels into super-voxels using an efficient graph-based segmentation scheme

…

super-voxel representation works better to separate different instances where the instance boundaries in 3D space is easier to identify thanks to the geometry continuity or local convexity constraints
