# Open-Vocabulary Instance Segmentation on MARIS in-domain (val) Source: [Open-Vocabulary Instance Segmentation on MARIS in-domain (val)]() Collection index: [llms.txt]() Data updated: 2026-03-18T07:51:41.186Z Evaluation of Open-Vocabulary Instance Segmentation performance on the validation split of the MARIS in-domain dataset, reporting Intersection, Open-Vocabulary, and Overall AP metrics. 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 | Open-Vocabulary Instance Segmentation | | Dataset (including any stated split) | MARIS in-domain (val) | | Metric | Overall Class mAP | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 28 of 28 | | 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 - [Overall Class mAP](): Higher is better; unit: PERCENT. - [Intersection Class mAP](): Higher is better; unit: PERCENT. - [Intersection Class AP50](): Higher is better; unit: PERCENT. - [Intersection Class AP75](): Higher is better; unit: PERCENT. - [Open-Vocabulary Class mAP](): Higher is better; unit: PERCENT. - [Open-Vocabulary Class AP50](): Higher is better; unit: PERCENT. - [Open-Vocabulary Class AP75](): Higher is better; unit: PERCENT. - [Overall Class AP50](): Higher is better; unit: PERCENT. - [Overall Class AP75](): Higher is better; unit: PERCENT. ## Recorded results | Method | Overall Class mAP | Result date | Report paper | | --- | --- | --- | --- | | MARIS | 56.71 | Not recorded | 68fa7c461e209131cea8d554 | | MAFT+ | 53.41 | Not recorded | 68fa7c461e209131cea8d554 | | FCCLIP | 52.17 | Not recorded | 68fa7c461e209131cea8d554 | | EOVSeg | 49.53 | Not recorded | 68fa7c461e209131cea8d554 | | SAN | 47.78 | Not recorded | 68fa7c461e209131cea8d554 | | ODISE | 46.95 | Not recorded | 68fa7c461e209131cea8d554 | | OVSeg | 46.41 | Not recorded | 68fa7c461e209131cea8d554 | | MARIS (Our Method) | 46.18 | Not recorded | 68fa7c461e209131cea8d554 | | MARIS | 44.37 | Not recorded | 68fa7c461e209131cea8d554 | | MAFT+ | 40.27 | Not recorded | 68fa7c461e209131cea8d554 | | MAFT+ | 40.08 | Not recorded | 68fa7c461e209131cea8d554 | | FCCLIP | 39.46 | Not recorded | 68fa7c461e209131cea8d554 | | FCCLIP | 39.26 | Not recorded | 68fa7c461e209131cea8d554 | | SAN | 36.05 | Not recorded | 68fa7c461e209131cea8d554 | | EOVSeg | 35.9 | Not recorded | 68fa7c461e209131cea8d554 | | ODISE | 34.71 | Not recorded | 68fa7c461e209131cea8d554 | | SAN | 34.05 | Not recorded | 68fa7c461e209131cea8d554 | | ODISE | 32.82 | Not recorded | 68fa7c461e209131cea8d554 | | MARIS (Our Method) | 32.62 | Not recorded | 68fa7c461e209131cea8d554 | | EOVSeg | 31.22 | Not recorded | 68fa7c461e209131cea8d554 | | OVSeg | 30.95 | Not recorded | 68fa7c461e209131cea8d554 | | OVSeg | 30.65 | Not recorded | 68fa7c461e209131cea8d554 | | MAFT+ | 30.05 | Not recorded | 68fa7c461e209131cea8d554 | | FCCLIP | 29.79 | Not recorded | 68fa7c461e209131cea8d554 | | SAN | 19.18 | Not recorded | 68fa7c461e209131cea8d554 | | OVSeg | 18.95 | Not recorded | 68fa7c461e209131cea8d554 | | EOVSeg | 18.9 | Not recorded | 68fa7c461e209131cea8d554 | | ODISE | 18.51 | Not recorded | 68fa7c461e209131cea8d554 | ### MARIS Overall Class mAP: 56.71.
