Semantic-Based Image Retrial in the VQ Compressed Domain using Image Annotation Statistical Models

A Framework Integrating Signal / Semantic Visual Characterizations for Conceptual Video Retrieval

Most of the video indexing and retrieval systems suffer from the lack of a comprehensive video model capturing the image semantic richness, the conveyed signal information and the spatial relations between visual entities. To remedy such shortcomings, we present in this paper a video model integrating visual semantics, spatial and signal characterizations. It relies on an expressive representat...

Paper TRECVid Semantic Indexing of Video: A 6-Year Ret- rospective

Semantic indexing, or assigning semantic tags to video samples, is a key component for content-based access to video documents and collections. The Semantic Indexing task has been run at TRECVid from 2010 to 2015 with the support of NIST and the Quaero project. As with the previous High-Level Feature detection task which ran from 2002 to 2009, the semantic indexing task aims at evaluating metho...

Semantic Transcoding: Making the World Wide Web More Understandable and Usable with External Annotations

This paper proposes an easy and simple method for constructing a super-structure on the Web which provides current Web contents with new value and new means of use. The super-structure is based on external annotations to Web documents. We have developed a system for any user to annotate any element of any Web document with additional information. We have also developed a proxy that transcodes r...

A Two-time Model for Video Content Representation and Retrieval

This paper presents a temporal model of video for video retrieval systems. Time is the dimension that plays an essential role in the perception of video document content. The modelling of the different temporal characteristics of the video content is however a complicated problem. Our approach to this problem has consisted of distinguishing two different dimensions of time for video documents: ...
