Researchers from National University of Defense Technology, JD Explore Academy, and Meituan Inc. developed MotionTrack, a multi-object tracking framework that excels in scenarios with homogeneous appearances and non-linear motions by employing a learnable, Transformer-based motion predictor. The system achieved state-of-the-art results on challenging datasets like DanceTrack (58.2% HOTA) and SportsMOT (74.0% HOTA), demonstrating the effectiveness of its dual-granularity motion modeling.
Key insights
- A learned non-linear motion predictor, particularly one based on Transformer architecture, significantly outperforms traditional Kalman filters and LSTM-based models for multi-object tracking in complex motion scenarios.
- The Dual-granularity Information Fusion Layer, combining Multi-Head Self-Attention for token-level and Dynamic MLP for channel-level feature processing, is crucial for capturing comprehensive motion dynamics.
- For the evaluated scenarios, focusing on individual object motion dynamics (isolated prediction) is more effective than attempting to model inter-object interactions using complex agent-aware attention.
