Boosting Single-Frame 3D Object Detection by Simulating Multi-Frame Point Clouds

no code implementations3 Jul 2022 Wu Zheng, Li Jiang, Fanbin Lu, Yangyang Ye, Chi-Wing Fu

To boost a detector for single-frame 3D object detection, we present a new approach to train it to simulate features and responses following a detector trained on multi-frame point clouds.

Boosting 3D Object Detection by Simulating Multimodality on Point Clouds

no code implementations CVPR 2022 Wu Zheng, Mingxuan Hong, Li Jiang, Chi-Wing Fu

This paper presents a new approach to boost a single-modality (LiDAR) 3D object detector by teaching it to simulate features and responses that follow a multi-modality (LiDAR-image) detector.

SE-SSD: Self-Ensembling Single-Stage Object Detector From Point Cloud

1 code implementation CVPR 2021 Wu Zheng, Weiliang Tang, Li Jiang, Chi-Wing Fu

Lastly, to better exploit hard targets, we design an ODIoU loss to supervise the student with constraints on the predicted box centers and orientations.

CIA-SSD: Confident IoU-Aware Single-Stage Object Detector From Point Cloud

1 code implementation5 Dec 2020 Wu Zheng, Weiliang Tang, Sijin Chen, Li Jiang, Chi-Wing Fu

Existing single-stage detectors for locating objects in point clouds often treat object localization and category classification as separate tasks, so the localization accuracy and classification confidence may not well align.

Relational Network for Skeleton-Based Action Recognition

no code implementations7 May 2018 Wu Zheng, Lin Li, Zhao-Xiang Zhang, Yan Huang, Liang Wang

We introduce the Recurrent Relational Network to learn the spatial features in a single skeleton, followed by a multi-layer LSTM to learn the temporal features in the skeleton sequences.
