Datasets:
tasksource/refcoco-grounding v2026.10.16
- Add 100,000 training, 24,527 validation and 30,903 test referring-expression decisions from RefCOCO, RefCOCO+ and RefCOCOg.
- Share unchanged COCO2014 images across the three views. Choices are native object boxes; no synthetic distractors.
- Reserve held-out photographs across variants by both image ID and image hash. Preserve original split names in metadata; native test subsets share the canonical test split.
- Record original per-image Flickr licenses and source revisions. Noncommercial and unresolved terms are retained explicitly.
