| 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 materials looked natural in the tested upscale; findings cover this fixed image only. |
| 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. | Achieves 27.49 dB full-image PSNR, 0.8913 SSIM, and 16.04 dB calibration plate PSNR; carved wood on "REALTEST 2026" and brass knuckles are crisp and natural (edge_corr=0.6673, hf_ratio=0.5159). |
