Abstract
En 中文
Traditional image restoration methods treat degradation types independently, neglecting intrinsic connections between degradation phenomena. While All-in-one models handle multiple degradations within single networks, they fail to fully exploit correlations between different degradation types, limiting performance in complex scenarios. This paper proposes FSDRNet (Frequency-Spatial Collaborative Dynamic Recovery Network), achieving efficient restoration through multi-domain collaborative enhancement and dynamic routing. The spatial module employs balanced feature mixing attention (EFMA) for precise local texture characterization, while the frequency domain module extracts global structural patterns via Fourier transforms, transmitting key information through degradation guidance signals to establish unidirectional enhancement. The network adaptively adjusts parameters according to degradation types and achieves precise restoration through physically-guided specialized filters. Extensive experiments demonstrate FSDRNet's excellent performance across denoising, deblurring, dehazing, deraining, and low-light enhancement tasks, achieving 28.52dB average PSNR while exhibiting significant generalization capability for unknown compound degradations.
