Restoration quality against scale factors under multiple invertible image downscaling solutions. The downscaling/upscaling realization includes both Bicubic interpolation (BI+BI), BI+state-of-the-art scale-arbitrary SR method (BI+ArbRCAN [8]), scale-fixed invertible image downscaling methods (CAR+EDSR [4] and IRN [6]), and our proposed AIDN. They are evaluated on the Urban100 [9] dataset.
