SUPIR Image Upscaling Workflow

SUPIR (Scaling UP Image Restoration) image upscaling technology is an innovative solution based on deep learning models. Its core principle combines the prior knowledge of generative diffusion models (such as SDXL). Compared to traditional interpolation upscaling, SUPIR can reconstruct more natural detail textures during the upscaling process, especially excelling in high-frequency information areas such as faces and fabric textures.
