Weakly-supervised HOI Detection via Prior-guided Bi-level Representation Learning

no code implementations2 Mar 2023 Bo Wan, Yongfei Liu, Desen Zhou, Tinne Tuytelaars, Xuming He

Human object interaction (HOI) detection plays a crucial role in human-centric scene understanding and serves as a fundamental building-block for many vision tasks.

Single Image 3D Object Estimation with Primitive Graph Networks

1 code implementation9 Sep 2021 Qian He, Desen Zhou, Bo Wan, Xuming He

To address those challenges, we adopt a primitive-based representation for 3D object, and propose a two-stage graph network for primitive-based 3D object estimation, which consists of a sequential proposal module and a graph reasoning module.

Relation-aware Instance Refinement for Weakly Supervised Visual Grounding

1 code implementation CVPR 2021 Yongfei Liu, Bo Wan, Lin Ma, Xuming He

Visual grounding, which aims to build a correspondence between visual objects and their language entities, plays a key role in cross-modal scene understanding.

Learning Cross-modal Context Graph for Visual Grounding

2 code implementations20 Nov 2019 Yongfei Liu, Bo Wan, Xiaodan Zhu, Xuming He

To address their limitations, this paper proposes a language-guided graph representation to capture the global context of grounding entities and their relations, and develop a cross-modal graph matching strategy for the multiple-phrase visual grounding task.

Pose-aware Multi-level Feature Network for Human Object Interaction Detection

1 code implementation ICCV 2019 Bo Wan, Desen Zhou, Yongfei Liu, Rongjie Li, Xuming He

Reasoning human object interactions is a core problem in human-centric scene understanding and detecting such relations poses a unique challenge to vision systems due to large variations in human-object configurations, multiple co-occurring relation instances and subtle visual difference between relation categories.
