Synthetic Visual Genome 2: Extracting Large-scale Spatio-Temporal Scene Graphs from Videos
This paper introduces Synthetic Visual Genome 2 (SVG2), a large-scale automated panoptic video scene graph dataset with over 636K videos, and presents TRaSER, a novel model that leverages trajectory-aligned token mechanisms to significantly outperform existing baselines in scene graph generation and downstream video question answering tasks.
