New ID-VTG Task Enhances Video Temporal Grounding with Image-Text Queries

Researchers have introduced Image-Disambiguated Video Temporal Grounding (ID-VTG), a new task designed to improve the localization of specific events in videos when text queries alone are insufficient. This method uses a combination of a reference image and a text description to pinpoint segments where a particular instance performs a described action. To support this task, two benchmarks, IDVTG-Gym and IDVTG-InternVid, have been created, featuring complex scenarios with similar entities and temporal distractors. The proposed Visually-Guided Disambiguation Aggregation (VGD-Agg) framework utilizes a dual-branch architecture to efficiently generate and refine event proposals, achieving state-of-the-art results.
