Arbitrary-scale super-resolution is a raising research topic with tremendous application potentials. Prior CNN-based SR approaches usually apply to only one fixed resolution scale, and thus unable to adjust their output dimension without changing the low-resolution input. Such design creates a huge gap between academic research and practical usage, and a majority of image up-sampling applications, even sensitive to precision, still heavily relied on bicubic interpolation despite its poor quality.
Super Mario World Widescreen is your beloved Mario World SNES game but in the 16:9 resolution. This is possible by expanding the horizontal resolution by 96 pixels, increasing resolution from 256x224 to 352x224. Since the original SNES does not have this resolution, the emulator focused into high definition mods bsnes-hd must be used.
