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

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

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