Infrared Object Tracking via Complementary Dual-domain Interaction with Target-guided Frequency Transformation

Infrared Object Tracking (IOT) is challenging due to the low contrast of infrared images, which limits effective spatial feature extraction. Although recent works have explored frequency-domain information, their utilization remains insufficient, and fusion strategies either retain redundancy or fail to fully explore distinctive differences, thus limiting complementary enhancement. To overcome this, we propose a novel tracker that introduces a Target-guided Frequency Transformation Module (TFTM) and a Dual-domain Interactive Fusion Network (DIFN). The former extracts multi-frequency representations across scales and orientations, guided by an adaptive mask strategy to suppress background interference. The latter fuses the two domains with differentiated attention to achieve complementary enhancement. Extensive experiments show that our approach achieves superior performance over state-of-the-art trackers, highlighting the effectiveness of comprehensive frequency-domain integration in infrared object tracking.
