- Its lynx example contrasts five enlargement methods and warns that convincing generated fur may not match the original detail.
Field notes
The benchmark starts with 12 public-domain or CC0 images, reduces them by four times, and compares five enlargement methods against the originals using PSNR, SSIM and LPIPS. One example isolates a 128 × 128-pixel lynx-fur crop, showing how a model can create plausible detail that does not align with the source. The two listed browser tools also handle practical image tasks: compression across JPEG, WebP and AVIF, and image comparison with a difference heat map.
