FPGA-Based Real-Time Deblurring and Enhancement for UAV-Captured Infrared Imagery

In response to the inherent limitations of uncooled infrared imaging devices and the image degradation caused by UAV (Unmanned Aerial Vehicle) platform motion, resulting in low contrast and blurred details, a novel single-image blind deblurring and enhancement network is proposed for UAV infrared imagery. This network achieves global blind deblurring and local feature enhancement, laying a foundation for subsequent high-level vision tasks. The proposed architecture comprises three key modules: feature extraction, feature fusion, and simulated diffusion. Furthermore, a region-specific pixel loss is introduced to strengthen local feature perception, while a progressive training strategy is adopted to optimize model performance. Experimental results on public infrared datasets demonstrate that the presented method outperforms state-of-the-art methods HCTIRdeblur, reducing parameter count by 18.4%, improving PSNR by 10.7%, and decreasing edge inference time by 25.6%. This work addresses critical challenges in UAV infrared image processing and offers a promising solution for real-world applications.
