# Visual Grounding on ReferCOCOg (val-u) Source: [Visual Grounding on ReferCOCOg (val-u)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:34:37.966Z Evaluation of Visual Grounding performance on the validation-unseen split (val-u) of the ReferCOCOg dataset, specifically reporting accuracy at 0.5 IoU. 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 | Visual Grounding | | Dataset (including any stated split) | ReferCOCOg (val-u) | | Metric | Accuracy@0.5 IoU | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 6 of 6 | | 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 - [Accuracy@0.5 IoU](): Higher is better; unit: PERCENT. ## Recorded results | Method | Accuracy@0.5 IoU | Result date | Report paper | | --- | --- | --- | --- | | mPLUG-2 | 84.7 | Not recorded | 68fa6f461e209131cea44b05 | | OFA Large | 84.54 | Not recorded | 68fa6f461e209131cea44b05 | | UNICORN | 83.44 | Not recorded | 68fa6f461e209131cea44b05 | | MDETR | 81.64 | Not recorded | 68fa6f461e209131cea44b05 | | VILLA | 76.18 | Not recorded | 68fa6f461e209131cea44b05 | | UNITER | 74.86 | Not recorded | 68fa6f461e209131cea44b05 | ### mPLUG-2 Accuracy@0.5 IoU: 84.7.
