LongVU

What is LongVU ?

LongVU is an innovative long video language understanding model designed for efficient processing and analysis of long video content. It greatly reduces the number of video tags through a unique space-time adaptive compression mechanism while preserving key visual details. This technological breakthrough allows LongVU to process large numbers of video frames within a limited context length, significantly improving the understanding and analysis capabilities of long video content.

Who needs LongVU ?

LongVU 's target users include:

Researchers and developers: Focus on the field of video content analysis and understanding, especially professionals who need to deal with long videos.

Enterprises and institutions: We hope to apply the latest artificial intelligence technology in video analysis to improve efficiency and accuracy.

Teams with limited resources: users who need to implement high-performance video understanding under limited computing resources.

LongVU usage scenarios

1. Video content details query: Users ask about specific scenes in the video, and LongVU can provide a detailed description.

2. Action recognition: The user asks questions about specific actions in the video, and LongVU can accurately identify and answer them.

3. Object motion analysis: Users need to understand the movement direction of a specific object in the video, and LongVU can accurately describe its motion trajectory.

LongVU 's core advantages

High-efficiency compression mechanism: Use DINOv2 features to remove redundant frames and reduce computing burden.

Cross-modal query: Selectively reduce frame features through text-guided cross-modal query.

Time-dependence analysis: Spatial marking reduction is performed based on inter-frame time dependence to improve processing efficiency.

Excellent performance: Go beyond existing methods in a variety of video understanding benchmarks, especially at handling up to an hour-long video task.

Lightweight design: supports lightweight large language models, realizes high-performance video understanding, and is suitable for environments with limited resources.
