Voxel Set Transformer: A Set-to-Set Approach to 3D Object Detection from Point Clouds

1 code implementation19 Mar 2022 Chenhang He, Ruihuang Li, Shuai Li, Lei Zhang

VoxSeT is built upon a voxel-based set attention (VSA) module, which reduces the self-attention in each voxel by two cross-attentions and models features in a hidden space induced by a group of latent codes.

A Dual Weighting Label Assignment Scheme for Object Detection

1 code implementation18 Mar 2022 Shuai Li, Chenhang He, Ruihuang Li, Lei Zhang

Existing LA methods mostly focus on the design of pos weighting function, while the neg weight is directly derived from the pos weight.

Class-Balanced Pixel-Level Self-Labeling for Domain Adaptive Semantic Segmentation

1 code implementation18 Mar 2022 Ruihuang Li, Shuai Li, Chenhang He, Yabin Zhang, Xu Jia, Lei Zhang

One popular solution to this challenging task is self-training, which selects high-scoring predictions on target samples as pseudo labels for training.

Aug3D-RPN: Improving Monocular 3D Object Detection by Synthetic Images with Virtual Depth

no code implementations28 Jul 2021 Chenhang He, Jianqiang Huang, Xian-Sheng Hua, Lei Zhang

Current geometry-based monocular 3D object detection models can efficiently detect objects by leveraging perspective geometry, but their performance is limited due to the absence of accurate depth information.

Structure Aware Single-Stage 3D Object Detection From Point Cloud

1 code implementation CVPR 2020 Chenhang He, Hui Zeng, Jianqiang Huang, Xian-Sheng Hua, Lei Zhang

The auxiliary network is jointly optimized, by two point-level supervisions, to guide the convolutional features in the backbone network to be aware of the object structure.
