Linfeng Dong, Yuchen Yang, Hao Wu +4
We introduce RacketVision, a novel dataset and benchmark for advancing computer vision in sports analytics, covering table tennis, tennis, and badminton. The dataset is the first t…
Learnable SMPLify: A Neural Solution for Optimization-Free Human Pose Inverse Kinematics
Yuchen Yang, Linfeng Dong, Wei Wang +2
In 3D human pose and shape estimation, SMPLify remains a robust baseline that solves inverse kinematics (IK) through iterative optimization. However, its high computational cost li…
SGA-INTERACT: A 3D Skeleton-based Benchmark for Group Activity Understanding in Modern Basketball Tactic
Yuchen Yang, Wei Wang, Yifei Liu +5
Group Activity Understanding is predominantly studied as Group Activity Recognition (GAR) task. However, existing GAR benchmarks suffer from coarse-grained activity vocabularies an…
