Product Details

LongVU is an innovative long video language understanding model that reduces the number of video tags through a spatiotemporal adaptive compression mechanism while retaining visual details in long videos. The importance of this technology lies in its ability to process a large number of video frames with only a small loss of visual information within the limited context length, significantly improving the ability to understand and analyze long video content. LongVU outperforms existing methods on multiple video understanding benchmarks, especially on the task of understanding hour-long videos. Additionally, LongVU is able to efficiently scale to smaller model sizes while maintaining state-of-the-art video understanding performance.

Main Features

1
Use DINOv2 features to remove redundant frames with high similarity
2
Selective frame feature reduction using text-guided cross-modal querying
3

DenseAV

DenseAV

DenseAV is a novel dual-encoder localization architecture that learns high-resolution, semantically meaningful audio-visual alignment features by watching videos. It is able to discover the "meaning" of words and the "place" of sounds without explicit localization supervision, and automatically discovers and differentiates between these two types of associations. DenseAV’s localization capabilities come from a new multi-head feature aggregation operator that directly compares dense image and audio representations for comparative learning. Furthermore, DenseAV significantly surpasses the previous state-of-the-art on semantic segmentation tasks and outperforms ImageBind on cross-modal retrieval using less than half the parameters.
