Denseav
Overview :
DenseAV is a novel dual-encoder localization architecture that learns high-resolution, semantically meaningful audio-visual alignment features by observing videos. It can discover the "meaning" of words and the "location" of sounds without requiring explicit localization supervision, and automatically discovers and distinguishes between these two types of associations. DenseAV's localization capability stems from a new multi-head feature aggregation operator, which directly compares dense image and audio representations through contrastive learning. Additionally, DenseAV significantly outperforms previous art on semantic segmentation tasks and surpasses ImageBind in cross-modal retrieval using less than half the parameters.
Target Users :
DenseAV is suitable for researchers and developers who need to automatically extract semantic information from video content, particularly in fields where audio-visual content analysis is conducted without explicit labeled data.
Use Cases
In natural language processing, used to understand dialogue content and scenes in videos.
In video content analysis, used to identify and locate key sounds and objects in videos.
In multimedia retrieval systems, used to improve retrieval effectiveness based on sound and language.
Features
Discover the meaning of words and the location of sounds in videos without supervision.
Utilizes multi-head feature aggregation operators for contrastive learning.
Learns in a self-supervised manner without labels.
Outperforms previous art on semantic segmentation tasks.
Surpasses ImageBind in cross-modal retrieval using fewer parameters.
Contributed two new datasets for improving audio-visual representation evaluation.
