FOLT introduces a real-time, motion-centric multiple object tracking framework tailored for UAV-captured videos, enhancing detection and motion prediction through flow-guided modules. The approach achieves state-of-the-art accuracy, with a MOTA of 42.1 and IDF1 of 56.9 on Visdrone, while maintaining high inference speeds.
Key insights
- Appearance features are highly unreliable for multiple object tracking in UAV videos, making a motion-centric approach more effective.
- Optical flow can be effectively integrated to augment object detection features, improving performance for small and motion-blurred objects by providing temporal context.
- Learning motion predictions directly from local optical flow provides a more robust and accurate alternative to traditional state-space models for objects with large and irregular movements.
