In this supplemental material, we first provide additional ablation experiments on the activation function, the normalization layer and the introduced frequency loss in Sec. 1. Our ShuffleMixercan be applied toother restoration tasks. Table 1: Ablation experiments forcomponents oftheShuffleMixerLayer and the frequencyloss function. We evaluate them respectively on the developed tiny model and train them on the 4 DIV2Kdataset. Why does ShuffleMixer perform poorly on PSNR?This result may be caused by the luminance differences in some local areas.
