PointDC:Unsupervised Semantic Segmentation of 3D Point Clouds via Cross-modal Distillation and Super-Voxel Clustering (ICCV 2023)

Overview

We propose an unsupervised point clouds semantic segmentation framework, called PointDC.

NOTE

There are two projects deployed here. pointdc_mk is based on MinkowskiEngine.

TODO

  • Release code based on Minkowski and model weight files
  • Release code based on SpConv and model weight files
  • Release Spare Feature Volume files
