About

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

Visit our <a href="https://pointcloud-c.github.io/home" target='_blank'>project page</a> to explore more details. 🌱

*Note: Standalone indicates whether or not the method is a standalone architecture or a combination with augmentation or pretrain.

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.

TODO List

• Initial release. 🚀
• Add license. See here for more details.
• Release test sets. Download ModelNet-C and ShapeNet-C from our <a href="https://pointcloud-c.github.io/home" target='_blank'>project page</a>.
• Add evaluation scripts for classification models.
• Add evaluation scripts for part segmentation models.
• Add competition details.
• Clean and retouch codebase.
