SCR-Guided Difficulty-Aware Optimization for Infrared Small Target Detection
Researchers have developed a new framework called REEM (Reweighted Explicit-visibility Enhanced Modulation) to improve infrared small target detection. This method incorporates Signal-to-Clutter Ratio (SCR) as a prior during training, using a differentiable modulation to enhance the learning signal for low-visibility targets. REEM integrates seamlessly into existing U-Net-based MSHNet architectures without adding parameters or increasing inference time. Experiments show REEM consistently improves detection accuracy and reduces false alarms, particularly in challenging low-visibility scenarios. AI
