Researchers have developed Pocket-STVG (P-STVG), a new lightweight architecture designed for Spatio-Temporal Video Grounding (STVG). This system aims to accurately locate spatio-temporal tubes in videos that correspond to natural language queries. P-STVG achieves this by efficiently combining pre-trained components, including a temporal-aware video encoder based on MobileViCLIP and a spatial encoder-decoder derived from MDETR, rather than relying on large, end-to-end models. The architecture requires fewer than 90 million parameters and offers a favorable performance-efficiency trade-off, performing comparably to existing weakly supervised methods and outperforming earlier zero-shot approaches at a significantly lower computational cost.
