Detail Preserved Point Cloud Completion via Separated Feature Aggregation

1 code implementation ECCV 2020 Wenxiao Zhang, Qingan Yan, Chunxia Xiao

In this work, instead of using a global feature to recover the whole complete surface, we explore the functionality of multi-level features and aggregate different features to represent the known part and the missing part separately.

PC$^2$-PU: Patch Correlation and Point Correlation for Effective Point Cloud Upsampling

1 code implementation20 Sep 2021 Chen Long, Wenxiao Zhang, Ruihui Li, Hao Wang, Zhen Dong, Bisheng Yang

Point cloud upsampling is to densify a sparse point set acquired from 3D sensors, providing a denser representation for the underlying surface.

Learning Long-Range Information with Dual-Scale Transformers for Indoor Scene Completion

no code implementations ICCV 2023 Ziqi Wang, Fei Luo, Xiaoxiao Long, Wenxiao Zhang, Chunxia Xiao

Due to the limited resolution of 3D sensors and the inevitable mutual occlusion between objects, 3D scans of real scenes are commonly incomplete.

Enhancing Human-Centered Dynamic Scene Understanding via Multiple LLMs Collaborated Reasoning

no code implementations15 Mar 2024 Hang Zhang, Wenxiao Zhang, Haoxuan Qu, Jun Liu

Human-centered dynamic scene understanding plays a pivotal role in enhancing the capability of robotic and autonomous systems, in which Video-based Human-Object Interaction (V-HOI) detection is a crucial task in semantic scene understanding, aimed at comprehensively understanding HOI relationships within a video to benefit the behavioral decisions of mobile robots and autonomous driving systems.
