| Fixture findings | Under the 2048px standard anchor, BIRME's local WebGPU super-resolution outputs a 2048x2048 native PNG with 26.97 dB PSNR, 0.8897 SSIM, 0.6668 edge correlation (+17.9% over bicubic baseline), and 16.08 dB plate PSNR, completing in 60.3s purely offline on the client. | Text and highlights looked natural in this 4× result; free use remains credit-limited. |
| Original historical observation | BIRME AI Enhance runs purely offline via browser WebGPU/WASM, upscaling 1024x1024 to 2048x2048 with an edge correlation of 0.6668, delivering significantly better detail than bicubic interpolation. | VanceAI 4x super-resolution achieves PSNR = 26.86 dB and SSIM = 0.9717 on our 512→2048 restoration benchmark (03_download.png), preserving natural wood-carved lettering, metallic highlights, and apple surface sheen with no-login unwatermarked delivery. |
| Suitable uses · historical assessment | Users needing no-login, 100% private, client-side AI image super-resolution without uploading files to external servers | Designers and e-commerce users seeking no-login unwatermarked 4x/8x super-resolution combined with sharpening, denoising, or old-photo restoration |
