Area of Science:

• Computer Vision
• Artificial Intelligence
• Robotics

Background:

• Multimodal multi-object tracking is crucial for autonomous driving, using visual, auditory, and linguistic signals.
• Existing methods struggle with effective multimodal fusion, often neglecting frequency-domain cues and temporal semantic alignment, leading to tracking drift.

Purpose of the Study:

• To propose SynTrackThinking, an integrated framework addressing limitations in current multimodal tracking.
• To enhance representation learning with frequency-domain cues and improve temporal reasoning for robust tracking.

Main Methods:

• Developed an explainable multimodal-domain cross-attention fusion module (EMCFM) for coordinated spatial and frequency domain attention.
• Implemented a multimodal contrastive tracking learning (MCTL) strategy to maintain semantic and temporal coherence across modalities.

Main Results:

• SynTrackThinking demonstrated consistent gains in tracking precision, robustness, and generalization.
• The framework effectively handles complex cross-modal interactions and long-term temporal dependencies.

Conclusions:

• SynTrackThinking offers a scalable and dependable solution for real-world autonomous tracking.
• The proposed approach advances multimodal fusion and temporal reasoning in object tracking.
