These are recorded outputs from the deployed upscaling service. Compare the images, check the dimensions, and download the originals to judge for yourself.
All examples use 2× output. Recorded processing times range from 110.3 to 485.0 seconds on a shared 1-core CPU / 2 GB server, with no GPU. Times exclude upload, queue, and download, and vary with server load.

Image credits & a note on detail
Public examples are provided by scikit-image, with individual source and licensing information above. These public demonstration images remain available; private uploads follow the service’s 24-hour retention schedule.
AI may reinterpret textures, faces, and fine patterns. A larger output is not a guarantee that every detail is more accurate. The working canvas is capped at 960 × 1280 pixels (or the rotated equivalent), and larger exports may use interpolation. These examples were not evaluated with a standardized degradation benchmark, so no PSNR or other quality score is claimed.
