Unlocking the Potential of Grounding DINO in Videos: Parameter-Efficient Adaptation for Limited-Data Spatial-Temporal Localization

Zanyi Wang, Fan Li, Dengyang Jiang +4

Spatio-temporal video grounding (STVG) aims to localize queried objects within dynamic video segments. Prevailing fully-trained approaches are notoriously data-hungry. However, gat…

Deforming Videos to Masks: Flow Matching for Referring Video Segmentation

Zanyi Wang, Dengyang Jiang, Liuzhuozheng Li +6

Referring Video Object Segmentation (RVOS) requires segmenting specific objects in a video guided by a natural language description. The core challenge of RVOS is to anchor abstrac…
