New GRVS task and Sekai framework advance video segmentation with dynamic event memory

Researchers have introduced a new task called Generalized Reasoning Video Segmentation (GRVS) to address the dynamic nature of object identification in streaming videos. Unlike previous methods that assumed fixed target objects, GRVS accounts for evolving target sets based on accumulating events and query relevance over time. To evaluate GRVS, a benchmark named Isekai was developed, comprising 60 videos and 197 queries. The proposed framework, Sekai, utilizes an Event Memory Reasoner to manage evolving target states and a Memory-Grounded Decoder to locate valid targets in current frames, demonstrating a 3.2-point improvement over existing online RVS methods.
