We propose a new neural network module dubbed EdgeConv suitable for CNN-based high-level tasks on point clouds including classification and segmentation. EdgeConv is differentiable and can be plugged into existing architectures.
DGCNN is the author's re-implementation of Dynamic Graph CNN, which achieves state-of-the-art performance on point-cloud-related high-level tasks including category classification, semantic segmentation and part segmentation.
Further information please contact Yue Wang and Yongbin Sun.
The classification experiments in our paper are done with the pytorch implementation.
- pytorch-geometric
- pytorch-dgcnn (This implementation on S3DIS achieves significant better results than our tensorflow implementation)
