# Nighttime Image Dehazing on UNREAL-NH Source: [Nighttime Image Dehazing on UNREAL-NH]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:03:26.856Z Evaluation of Nighttime Image Dehazing performance on the UNREAL-NH dataset, measured using SSIM and PSNR. 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 | Nighttime Image Dehazing | | Dataset (including any stated split) | UNREAL-NH | | Metric | SSIM | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 32 of 32 | | 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 - [SSIM](): Higher is better; unit: SCALAR. - [PSNR](): Higher is better; unit: SCALAR. ## Recorded results | Method | SSIM | Result date | Report paper | | --- | --- | --- | --- | | SFSNiD | 0.862 | Not recorded | 68fa72b71e209131cea58209 | | MSBDN | 0.827 | Not recorded | 68fa72b71e209131cea58209 | | 4KDehazing | 0.774 | Not recorded | 68fa72b71e209131cea58209 | | Fourmer | 0.772 | Not recorded | 68fa72b71e209131cea58209 | | DF | 0.77 | Not recorded | 68fa72b71e209131cea58209 | | GD | 0.767 | Not recorded | 68fa72b71e209131cea58209 | | MITNet | 0.766 | Not recorded | 68fa72b71e209131cea58209 | | M3KE | 0.758 | Not recorded | 695c970053fdd5c361743686 | | DeHamer | 0.74 | Not recorded | 68fa72b71e209131cea58209 | | AECRNet | 0.731 | Not recorded | 68fa72b71e209131cea58209 | | SFSNiD | 0.729 | Not recorded | 695c970053fdd5c361743686 | | NightHaze | 0.725 | Not recorded | 695c970053fdd5c361743686 | | NightEnhance | 0.721 | Not recorded | 695c970053fdd5c361743686 | | CORUN | 0.711 | Not recorded | 695c970053fdd5c361743686 | | FSDGN | 0.702 | Not recorded | 68fa72b71e209131cea58209 | | DEANet | 0.701 | Not recorded | 695c970053fdd5c361743686 | | NightHazeFormer | 0.701 | Not recorded | 695c970053fdd5c361743686 | | DCMPNet | 0.7 | Not recorded | 695c970053fdd5c361743686 | | NightDeFog | 0.699 | Not recorded | 695c970053fdd5c361743686 | | MITNet | 0.694 | Not recorded | 695c970053fdd5c361743686 | | SGDN | 0.692 | Not recorded | 695c970053fdd5c361743686 | | DehazeFormer | 0.689 | Not recorded | 695c970053fdd5c361743686 | | MSBDN | 0.683 | Not recorded | 695c970053fdd5c361743686 | | MRP | 0.671 | Not recorded | 695c970053fdd5c361743686 | | OSFD | 0.67 | Not recorded | 695c970053fdd5c361743686 | | DeHamer | 0.664 | Not recorded | 695c970053fdd5c361743686 | | FFA | 0.662 | Not recorded | 695c970053fdd5c361743686 | | C2P | 0.656 | Not recorded | 695c970053fdd5c361743686 | | Fourmer | 0.645 | Not recorded | 695c970053fdd5c361743686 | | GridDehazeNet | 0.633 | Not recorded | 695c970053fdd5c361743686 | | MRP | 0.467 | Not recorded | 68fa72b71e209131cea58209 | | OSFD | 0.443 | Not recorded | 68fa72b71e209131cea58209 | ### SFSNiD SSIM: 0.862.
