| 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. | Added detail while retaining overall structure; check newly generated texture against the input. |
| 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=25.77 dB · SSIM=0.9605 · edge_corr=0.6507 · hf_ratio=0.7040: unlike diffusive enhancers that heavily alter lighting and geometry, Leonardo's Aurora Precise mode injects rich high-frequency detail while preserving 0.9605 SSIM structural consistency. |
| Suitable uses · historical assessment | Not verified | Designers and AI artists who want the best balance between generative micro-texture sharpening (`hf_ratio=0.7040`) and structural fidelity (`SSIM=0.9605`), with ~30 free upscales per day |
