DMKPN: Image Deblurring Under Multi-Factor Aliasing Diffusion Degradation

ICASSP 2025accepted

Image degradation results from a combination of factors. Recently, CNN-based image deblurring methods have made significant progress, but they rely heavily on the accuracy of paired data, which is impractical to collect for every camera. To address this, we propose a physical model for natural image…
