R4D-Bench Summary R4D-Bench targets spatio-temporal referring segmentation in dynamic (4D) scenes: natural-language queries paired with pixel-accurate instance masks over time (COCO-style polygons or RLE, optional PNG unions), emphasizing motion, temporal relations (before / while / after), multi-target phrases, and distractor queries. The release contains 89 referring queries with dense mask ground truth across 12 scenes (from the per-scene *_queries.json files).… See the full description on the dataset page: https://huggingface.co/datasets/LiYacheng/r4d-bench-qa.
