CN: Channel Normalization For Point Cloud Recognition

no code implementations ECCV 2020 Zetong Yang, Yanan sun, Shu Liu, Xiaojuan Qi, Jiaya Jia

In 3D recognition, to fuse multi-scale structure information, existing methods apply hierarchical frameworks stacked by multiple fusion layers for integrating current relative locations with structure information from the previous level.

A Unified Query-based Paradigm for Point Cloud Understanding

1 code implementation2 Mar 2022 Zetong Yang, Li Jiang, Yanan sun, Bernt Schiele, Jiaya Jia

This is achieved by introducing an intermediate representation, i. e., Q-representation, in the querying stage to serve as a bridge between the embedding stage and task heads.

3DSSD: Point-based 3D Single Stage Object Detector

2 code implementations CVPR 2020 Zetong Yang, Yanan sun, Shu Liu, Jiaya Jia

Our method outperforms all state-of-the-art voxel-based single stage methods by a large margin, and has comparable performance to two stage point-based methods as well, with inference speed more than 25 FPS, 2x faster than former state-of-the-art point-based methods.
