# Grayscale Image Denoising on BSD68 104 (test) Source: [Grayscale Image Denoising on BSD68 104 (test)]() Collection index: [llms.txt]() Data updated: 2026-03-04T19:20:06.538Z Evaluation of grayscale image denoising performance on the specific BSD68 104 test set, 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 | Grayscale Image Denoising | | Dataset (including any stated split) | BSD68 104 (test) | | Metric | PSNR | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 31 of 31 | | 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 | | --- | --- | --- | --- | | ATD-U | 32.02 | Not recorded | 69a7bc972d603e6de3e3d653 | | SCUNet | 31.99 | Not recorded | 69a7bc972d603e6de3e3d653 | | Xformer | 31.98 | Not recorded | 69a7bc972d603e6de3e3d653 | | SwinIR | 31.97 | Not recorded | 69a7bc972d603e6de3e3d653 | | Restormer | 31.96 | Not recorded | 69a7bc972d603e6de3e3d653 | | DRUNet | 31.91 | Not recorded | 69a7bc972d603e6de3e3d653 | | DnCNN | 31.73 | Not recorded | 69a7bc972d603e6de3e3d653 | | IRCNN | 31.63 | Not recorded | 69a7bc972d603e6de3e3d653 | | FFDNet | 31.63 | Not recorded | 69a7bc972d603e6de3e3d653 | | BM3D | 31.08 | Not recorded | 69a7bc972d603e6de3e3d653 | | ATD-U | 29.56 | Not recorded | 69a7bc972d603e6de3e3d653 | | SCUNet | 29.55 | Not recorded | 69a7bc972d603e6de3e3d653 | | Xformer | 29.55 | Not recorded | 69a7bc972d603e6de3e3d653 | | Restormer | 29.52 | Not recorded | 69a7bc972d603e6de3e3d653 | | SwinIR | 29.5 | Not recorded | 69a7bc972d603e6de3e3d653 | | DRUNet | 29.48 | Not recorded | 69a7bc972d603e6de3e3d653 | | DnCNN | 29.23 | Not recorded | 69a7bc972d603e6de3e3d653 | | FFDNet | 29.19 | Not recorded | 69a7bc972d603e6de3e3d653 | | IRCNN | 29.15 | Not recorded | 69a7bc972d603e6de3e3d653 | | BM3D | 28.57 | Not recorded | 69a7bc972d603e6de3e3d653 | | SCUNet | 26.67 | Not recorded | 69a7bc972d603e6de3e3d653 | | Xformer | 26.65 | Not recorded | 69a7bc972d603e6de3e3d653 | | ATD-U | 26.65 | Not recorded | 69a7bc972d603e6de3e3d653 | | Restormer | 26.62 | Not recorded | 69a7bc972d603e6de3e3d653 | | DRUNet | 26.59 | Not recorded | 69a7bc972d603e6de3e3d653 | | SwinIR | 26.58 | Not recorded | 69a7bc972d603e6de3e3d653 | | RNAN | 26.48 | Not recorded | 69a7bc972d603e6de3e3d653 | | FFDNet | 26.29 | Not recorded | 69a7bc972d603e6de3e3d653 | | DnCNN | 26.23 | Not recorded | 69a7bc972d603e6de3e3d653 | | IRCNN | 26.19 | Not recorded | 69a7bc972d603e6de3e3d653 | | BM3D | 25.6 | Not recorded | 69a7bc972d603e6de3e3d653 | ### ATD-U PSNR: 32.02.
