# Image Denoising on CBSD68 (Noise Levels σ=15, 25, 50) Source: [Image Denoising on CBSD68 (Noise Levels σ=15, 25, 50)]() Collection index: [llms.txt]() Data updated: 2026-06-23T11:43:25.893Z Evaluation of Image Denoising performance on the CBSD68 dataset, reporting PSNR across three specific noise standard deviations (σ=15, 25, 50). 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) | CBSD68 | | Metric | PSNR (dB, σ=15) | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 16 of 16 | | 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 (dB, σ=15)](): Higher is better; unit: SCALAR. - [PSNR (dB, σ=25)](): Higher is better; unit: SCALAR. - [PSNR (dB, σ=50)](): Higher is better; unit: SCALAR. ## Recorded results | Method | PSNR (dB, σ=15) | Result date | Report paper | | --- | --- | --- | --- | | MLMIR | 34.44 | Not recorded | 6a3a13a7206542251d7c774e | | Restormer | 34.39 | Not recorded | 69e704a47d0172140ec7ede1 | | Perceive-IR | 34.38 | Not recorded | 6a3a13a7206542251d7c774e | | DSCA-Former | 34.35 | Not recorded | 69e704a47d0172140ec7ede1 | | VLU-Net | 34.35 | Not recorded | 6a3a13a7206542251d7c774e | | NLFeMF (25/15/9 nbr) | 34.34 | Not recorded | 69e704a47d0172140ec7ede1 | | CTNet | 34.32 | Not recorded | 69e704a47d0172140ec7ede1 | | NLFeMF (15/9/7 nbr) | 34.31 | Not recorded | 69e704a47d0172140ec7ede1 | | DRUNet | 34.3 | Not recorded | 69e704a47d0172140ec7ede1 | | NLFeMF (15/7/5 nbr) | 34.3 | Not recorded | 69e704a47d0172140ec7ede1 | | FSNet | 34.11 | Not recorded | 6a3a13a7206542251d7c774e | | SFNet | 34.09 | Not recorded | 6a3a13a7206542251d7c774e | | NLFeMF (15 nbr) | 33.98 | Not recorded | 69e704a47d0172140ec7ede1 | | DnCNN | 33.9 | Not recorded | 69e704a47d0172140ec7ede1 | | FFDNet | 33.87 | Not recorded | 69e704a47d0172140ec7ede1 | | BM3D | 33.52 | Not recorded | 69e704a47d0172140ec7ede1 | ### MLMIR PSNR (dB, σ=15): 34.44.
