SFMformer: A Spatial-Frequency Modulation Transformer for Lightweight Image Super-Resolution
It is observed that sparsification changes what it means to improve such a network, and a dual-branch spatial enhancement on the input of a progressive focused attention with a wavelet-domain modulation on its output is tested, forming SFMformer, which ranks first on 28 of 30 PSNR/SSIM entries across five benchmarks an...
