Large clean references with deliberately downscaled (and optionally JPEG-degraded) inputs for testing upscalers, super-resolution models, and enlarge-without-blur pipelines.
Clean 1024×1024 reference for super-resolution base A. Upscale the smaller inputs in this group toward this ground truth.
Bicubic downscale to 256×256 from the 1024px reference. Use as a super-resolution input.
Bicubic downscale to 128×128 from the 1024px reference. Use as a super-resolution input.
Bicubic downscale to 64×64 from the 1024px reference. Use as a super-resolution input.
256×256 bicubic downscale further JPEG-compressed at quality 35 — a harder super-resolution input with artefacts.
Clean 1024×1024 reference for super-resolution base B. Upscale the smaller inputs in this group toward this ground truth.
Bicubic downscale to 256×256 from the 1024px reference. Use as a super-resolution input.
Bicubic downscale to 128×128 from the 1024px reference. Use as a super-resolution input.
Bicubic downscale to 64×64 from the 1024px reference. Use as a super-resolution input.
256×256 bicubic downscale further JPEG-compressed at quality 35 — a harder super-resolution input with artefacts.
