HGL: Hierarchical Geometry Learning for Test-time Adaptation in 3D Point Cloud Segmentation

1 code implementation17 Jul 2024 Tianpei Zou, Sanqing Qu, Zhijun Li, Alois Knoll, Lianghua He, Guang Chen, Changjun Jiang

HGL comprises three complementary modules from local, global to temporal learning in a bottom-up manner. Technically, we first construct a local geometry learning module for pseudo-label generation.

MAP: MAsk-Pruning for Source-Free Model Intellectual Property Protection

1 code implementation CVPR 2024 Boyang Peng, Sanqing Qu, Yong Wu, Tianpei Zou, Lianghua He, Alois Knoll, Guang Chen, Changjun Jiang

In this paper, we target a practical setting where only a well-trained source model is available and investigate how we can realize IP protection.

PCDepth: Pattern-based Complementary Learning for Monocular Depth Estimation by Best of Both Worlds

no code implementations29 Feb 2024 Haotian Liu, Sanqing Qu, Fan Lu, Zongtao Bu, Florian Roehrbein, Alois Knoll, Guang Chen

Therefore, existing complementary learning approaches for MDE fuse intensity information from images and scene details from event data for better scene understanding.

TMA: Temporal Motion Aggregation for Event-based Optical Flow

1 code implementation ICCV 2023 Haotian Liu, Guang Chen, Sanqing Qu, Yanping Zhang, Zhijun Li, Alois Knoll, Changjun Jiang

In this paper, we argue that temporal continuity is a vital element of event-based optical flow and propose a novel Temporal Motion Aggregation (TMA) approach to unlock its potential.

BMD: A General Class-balanced Multicentric Dynamic Prototype Strategy for Source-free Domain Adaptation

1 code implementation6 Apr 2022 Sanqing Qu, Guang Chen, Jing Zhang, Zhijun Li, wei he, DaCheng Tao

Source-free Domain Adaptation (SFDA) aims to adapt a pre-trained source model to the unlabeled target domain without accessing the well-labeled source data, which is a much more practical setting due to the data privacy, security, and transmission issues.
