About

PointCloud-C is the very first test-suite for point cloud perception robustness analysis under corruptions. It includes two sets: ModelNet-C (ICML'22) for point cloud classification and ShapeNet-C (arXiv'22) for part segmentation.

Evaluation

Evaluation commands are provided in EVALUATE.md.

Customize Evaluation

We have provided evaluation utilities to help you evaluate on ModelNet-C using your own codebase. Please follow CUSTOMIZE.md.

Build PointCloud-C

You can manage to generate your own "PointCloud-C"! Follow the instructions in GENERATE.md.
