Upscale Reference A — 1024px
Clean 1024×1024 reference for super-resolution base A. Upscale the smaller inputs in this group toward this ground truth.
Super-resolution and upscale inputs
Large clean references with deliberately downscaled (and optionally JPEG-degraded) inputs for testing upscalers, super-resolution models, and enlarge-without-blur pipelines.
