| 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. | The tested 2× output was watermark-free with some edge recovery, at 1024px. |
| 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. | PSNR=27.57dB · SSIM=0.8918 (2x 1024×1024 unwatermarked PNG); ranks #1 in PSNR and SSIM among all 2x free upscalers with edge_corr=0.6496, hf_ratio=0.5289, and a blazing 1.74s Network-observed server wait. |
