ST4R-Splat: Spatio-Temporal Referring Segmentation in 4D Gaussian Splatting
CVPR 2026
Understanding objects in dynamic 4D environments via natural language is crucial yet underexplored. While existing methods focus on static 3D referring segmentation or open-vocabulary 4D querying, they struggle to ground complex spatio-temporal referring expressions in explicit 4D reconstructions. W
