FreqKD: Frequency-Decoupled Cross-Modal Knowledge Distillation for Infrared Object Detection
FreqKD uses strict MSE on low-frequency features and relaxed log-MSE (weight 0.1) on high-frequency features for RGB-to-IR distillation, reporting 2.4 mAP50 gain on KAIST pedestrian detection with transfer to other datasets and tasks.
