متن کاملA Context-Based Audiovisual Representation Model for Audiovisual Information Systems
In this paper we present a contextual representation model of audiovisual (AV) documents for AV information systems. In the rst part, we study AV medium, and show that AV intra-document context is always related to a user task seen as a general description task. We then present the AI-Strata model for AV description: audiovisual units (pieces of AV documents) are annotated with annotation eleme...
متن کاملAudiovisual source separation
Blind source separation (BSS) can be seen as a generalization of denoising a noisy signal when several sensors are available. Each of them records the same physical phenomenon in a different way: such a diversity is then useful to separate the present signals for instance by independent component analysis (ICA) or sparse component analysis (SCA) [1]. The main objective of speech separation/extr...
متن کاملAudiovisual Speech Synthesis
This paper presents the main approaches used to synthesize talking faces, and provides greater detail on a handful of these approaches. No system is described exhaustively, however, and, for purposes of conciseness, not all existing systems are reviewed. An attempt is made to distinguish between facial synthesis itself (i.e the manner in which facial movements are rendered on a computer screen)...
متن کاملAudiovisual Programs As Sources Of Language Input: An Overview
