| Measured fixture results | Tested scale: 4× | Tested scale: 2× |
| Fixture findings | The 4× upscale remains smooth and clean, achieving 26.89 dB PSNR and 0.8867 SSIM with legible main sign text, though fine high frequencies are smoother than generative diffusion models. | No obvious artifacts appeared in this 2× test; recovery of fine blurred edges remained limited. |
| Original historical observation | Uploaded 512×512 anchor image; selected By Dimensions mode setting target to 2048×2048 (4.0x upscale). Client HTML5 Canvas rendered deliverable in 3.41 seconds, achieving 26.89 dB PSNR, 0.8867 SSIM, and 15.07 dB plate PSNR. Deliverable remained clean and smooth; direct Base64 PNG download. | PSNR=27.34dB · SSIM=0.8924 (2x 1024×1024 JPG); Mode A GT exposes the underlying algorithm: edge_corr=0.5740 and hf_ratio=0.4018 sit barely above standard non-AI Bicubic interpolation (0.5656 / 0.3651), proving its 0.60s speed comes from a lightweight CNN/unsharp filter rather than deep super-resolution; Calibration plate PSNR=15.60dB: artifact-free, but recovers significantly less high-frequency edge detail than iLoveIMG or Upscale.media. |
