# Referring Image Segmentation on G-Ref hard UMD (val) Source: [Referring Image Segmentation on G-Ref hard UMD (val)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:11:12.478Z Evaluation of Referring Image Segmentation performance on the 'hard' subset of the UMD validation split of the G-Ref dataset, typically measured using object IoU (oIoU). 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 | Referring Image Segmentation | | Dataset (including any stated split) | G-Ref hard UMD (val) | | Metric | oIoU | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 14 of 14 | | 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 - [oIoU](): Higher is better; unit: PERCENT. ## Recorded results | Method | oIoU | Result date | Report paper | | --- | --- | --- | --- | | MagNet+ | 67.79 | Not recorded | 68fa72a31e209131cea57b98 | | PolyFormer | 67.76 | Not recorded | 68fa72a31e209131cea57b98 | | LISA-7B | 66.4 | Not recorded | 68fa72a31e209131cea57b98 | | SEEM | 65.7 | Not recorded | 68fa72a31e209131cea57b98 | | MagNet | 65.36 | Not recorded | 68fa72a31e209131cea57b98 | | ReLA | 65 | Not recorded | 68fa72a31e209131cea57b98 | | SADLR | 63.6 | Not recorded | 68fa72a31e209131cea57b98 | | MCRES | 63.51 | Not recorded | 68fa72a31e209131cea57b98 | | PVD | 63.13 | Not recorded | 68fa72a31e209131cea57b98 | | VPD | 63.12 | Not recorded | 68fa72a31e209131cea57b98 | | CoupAlign | 62.84 | Not recorded | 68fa72a31e209131cea57b98 | | LAVT | 61.24 | Not recorded | 68fa72a31e209131cea57b98 | | CRIS | 59.87 | Not recorded | 68fa72a31e209131cea57b98 | | VLT | 52.99 | Not recorded | 68fa72a31e209131cea57b98 | ### MagNet+ oIoU: 67.79.
