Fine-Grained Spatial and Verbal Losses for 3D Visual GroundingSombit Dey, Ozan Unal, Christos Sakaridis, Luc Van Gool WACV 2025 arxiv / code / website / We introduce two novel losses for 3D visual grounding: a visual-level offset loss on regressed vector offsets from each instance to the ground-truth referred instance and a language-related span loss on predictions for the word-level span of the referred instance in the description |
