| Measured fixture results | Tested scale: 4× | Tested scale: 1.46× |
| Fixture findings | Ran 4× upscaling locally with noise reduction and text retention; speed depends on the device. | Texture was retained in this fixture; free output was only 750px, about 1.46× enlargement. |
| Original historical observation | Waifu2x Unlimited (Swin-UNet Photo 4x) suppresses JPEG compression artifacts cleanly while preserving natural camera gradients (PSNR 28.34 dB, SSIM 0.895) in 2.63s via WebGPU, without introducing fake generative hallucinations. | PSNR=27.61dB (#1 highest pixel PSNR overall) · SSIM=0.8955 (#1 highest structural similarity overall); Edge gradient correlation edge_corr=0.6353 (#3 overall, +6.97% over Bicubic); hf_ratio=0.4482 (constrained by the free tier's 750×750 1.46x resolution cap); Calibration plate PSNR=16.01dB (#2 overall): exceptional fidelity with zero hallucinated artifacts on the wood sign or grating. |
| Suitable uses · historical assessment | Privacy-conscious users, anime/illustration and natural photo creators who want 100% free, unlimited 4x local GPU super-resolution without uploading files to any cloud server | Users prioritizing top pixel fidelity (highest PSNR/SSIM) who are satisfied with 750px free previews or willing to spend credits for 1024px HD |
