SAT-HMR: Real-Time Multi-Person 3D Mesh Estimation via Scale-Adaptive Tokens

no code implementations29 Nov 2024 Chi Su, Xiaoxuan Ma, Jiajun Su, Yizhou Wang

While current one-stage methods, which follow a DETR-style pipeline, achieve state-of-the-art (SOTA) performance with high-resolution inputs, we observe that this particularly benefits the estimation of individuals in smaller scales of the image (e. g., those far from the camera), but at the cost of significantly increased computation overhead.

AlphaChimp: Tracking and Behavior Recognition of Chimpanzees

1 code implementation22 Oct 2024 Xiaoxuan Ma, Yutang Lin, Yuan Xu, Stephan P. Kaufhold, Jack Terwilliger, Andres Meza, Yixin Zhu, Federico Rossano, Yizhou Wang

Understanding non-human primate behavior is crucial for improving animal welfare, modeling social behavior, and gaining insights into both distinctly human and shared behaviors.

Scaling Up Dynamic Human-Scene Interaction Modeling

no code implementations CVPR 2024 Nan Jiang, Zhiyuan Zhang, Hongjie Li, Xiaoxuan Ma, Zan Wang, Yixin Chen, Tengyu Liu, Yixin Zhu, Siyuan Huang

Confronting the challenges of data scarcity and advanced motion synthesis in human-scene interaction modeling, we introduce the TRUMANS dataset alongside a novel HSI motion synthesis method.
