Peng Wang, Yongcai Wang, Wang Chen, Hualong Cao, Kang Yang, Chunxu Li +2

CVPR 2026

Online 3D instance segmentation is a critical capability for embodied agents navigating in dynamic environments. However, a fundamental challenge remains in adapting powerful 2D foundation models, like SAM, to 3D online segmentation. Naively lifting SAM's 2D masks to 3D results in severe spatial fra

LA-MOTR: End-to-End Multi-Object Tracking by Learnable Association

Peng Wang, Yongcai Wang, Hualong Cao, Wang Chen, Deying Li

ICCV 2025poster

This paper proposes LA-MOTR, a novel Tracking-by-Learnable-Association framework that resolves the competing optimization objectives between detection and association in end-to-end Tracking-by-Attention (TbA) Multi-Object Tracking. Current TbA methods employ shared decoders for simultaneous object d…
