DiffFNO: Diffusion Fourier Neural Operator

Inference Time (ms) PSNR (dB) (a) PSNR and inference time for ×4 super-resolution (b) DiffFNO vs SRNO [54] † Corresponding author. * Work Done during the visit at Peking University. PSNR, including those beyond the training distribution. It also achieves this at lower inference time (Fig. 1 (a) ). Our approach sets a new standard in super-resolution, delivering both superior accuracy and computational efficiency.
