# Image Denoising on PolyU SIDD pre-trained real-world (test) Source: [Image Denoising on PolyU SIDD pre-trained real-world (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:56:14.214Z Evaluation of image denoising performance on the test split of the PolyU SIDD pre-trained real-world dataset, measured using PSNR and SSIM. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Image Denoising | | Dataset (including any stated split) | PolyU SIDD pre-trained real-world (test) | | Metric | PSNR | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 37 of 37 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [PSNR](): Higher is better; unit: SCALAR. - [SSIM](): Higher is better; unit: SCALAR. ## Recorded results | Method | PSNR | Result date | Report paper | | --- | --- | --- | --- | | LAN | 39.28 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 39.2 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 39.17 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 39.1 | Not recorded | 68fa763a1e209131cea6bf87 | | pretrained | 39.03 | Not recorded | 68fa763a1e209131cea6bf87 | | pretrained | 38.93 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 38.31 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 38.29 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 38.29 | Not recorded | 68fa763a1e209131cea6bf87 | | meta-learning | 38.25 | Not recorded | 68fa763a1e209131cea6bf87 | | meta-learning | 38.23 | Not recorded | 68fa763a1e209131cea6bf87 | | meta-learning | 38.23 | Not recorded | 68fa763a1e209131cea6bf87 | | meta-learning | 38.23 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 38.22 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 38.22 | Not recorded | 68fa763a1e209131cea6bf87 | | meta-learning | 38.2 | Not recorded | 68fa763a1e209131cea6bf87 | | meta-learning | 38.17 | Not recorded | 68fa763a1e209131cea6bf87 | | LAN | 38.16 | Not recorded | 68fa763a1e209131cea6bf87 | | last-layer | 38.14 | Not recorded | 68fa763a1e209131cea6bf87 | | last-layer | 38.14 | Not recorded | 68fa763a1e209131cea6bf87 | | last-layer | 38.13 | Not recorded | 68fa763a1e209131cea6bf87 | | last-layer | 38.13 | Not recorded | 68fa763a1e209131cea6bf87 | | last-layer | 38.13 | Not recorded | 68fa763a1e209131cea6bf87 | | last-layer | 38.12 | Not recorded | 68fa763a1e209131cea6bf87 | | pretrained | 38.1 | Not recorded | 68fa763a1e209131cea6bf87 | | full-trainable | 38.08 | Not recorded | 68fa763a1e209131cea6bf87 | | full-trainable | 38.07 | Not recorded | 68fa763a1e209131cea6bf87 | | full-trainable | 38.06 | Not recorded | 68fa763a1e209131cea6bf87 | | full-trainable | 38.04 | Not recorded | 68fa763a1e209131cea6bf87 | | full-trainable | 38.02 | Not recorded | 68fa763a1e209131cea6bf87 | | full-trainable | 37.99 | Not recorded | 68fa763a1e209131cea6bf87 | | first-layer | 37.95 | Not recorded | 68fa763a1e209131cea6bf87 | | first-layer | 37.93 | Not recorded | 68fa763a1e209131cea6bf87 | | first-layer | 37.83 | Not recorded | 68fa763a1e209131cea6bf87 | | first-layer | 37.76 | Not recorded | 68fa763a1e209131cea6bf87 | | first-layer | 37.67 | Not recorded | 68fa763a1e209131cea6bf87 | | first-layer | 37.47 | Not recorded | 68fa763a1e209131cea6bf87 | ### LAN PSNR: 39.28.
