Longvu
Overview :
LongVU is an innovative long video language understanding model that reduces the number of video annotations through a spatiotemporal adaptive compression mechanism while preserving visual details in lengthy videos. The importance of this technology lies in its ability to handle a large number of video frames while losing only a minimal amount of visual information within a limited context length, significantly enhancing long video content understanding and analysis capabilities. LongVU surpasses existing methods in various video understanding benchmark tests, particularly for tasks involving videos up to one hour long. Furthermore, LongVU can effectively scale down to smaller model sizes while maintaining state-of-the-art video understanding performance.
Target Users :
The target audience for LongVU includes researchers and developers in the field of video content analysis and understanding, particularly those who need to process lengthy video content and seek efficient video comprehension solutions with limited computational resources. Additionally, LongVU offers an advanced solution for enterprises and organizations interested in applying the latest artificial intelligence technologies in video analysis.
Use Cases
When users inquire about the details of video content, LongVU can provide detailed descriptions of video scenes.
If users ask questions about specific actions in the video, LongVU can accurately identify and answer.
When users need to understand the movement direction of specific objects in the video, LongVU can accurately identify and describe the object's motion.
Features
Utilizes DINOv2 features to remove highly similar redundant frames
Employs text-guided cross-modal querying for selective frame feature reduction
Reduces spatial annotations based on inter-frame temporal dependencies
Effectively processes a large number of video frames within limited context lengths
Outperforms existing methods in various video understanding benchmark tests
Supports lightweight large language models for high-performance video understanding
