STPro: Spatial and Temporal Progressive Learning for Weakly Supervised Spatio-Temporal Grounding

In this work, we study Weakly Supervised Spatio-Temporal Video Grounding (WSTVG), a challenging task of localizing subjects spatio-temporally in videos using only textual queries and no bounding box supervision. Inspired by recent advances in vision-language foundation models, we investigate their u…
