Semantic characterization, indexing and universal customized access to audiovisual content under controlled environments TIN2004-07860-C02

The main objective of this project is to research in the design of algorithms and the development of tools both oriented to automatic feature extraction in image sequences of controlled environments, additionally the further indexing, storage and customized access to the previously extracted and properly coded information out of those sequences. The project consists of to main stages: Informati...

MPEG-4 facial animation technology: survey, implementation, and results

The emerging MPEG-4 standard specifies an objectbased audiovisual representation framework, integrating both natural and synthetic content. Tools supporting three-dimensional facial animation will be standardized for the first time. To support facial animation decoders with different degrees of complexity, MPEG-4 uses a profiling strategy, which foresees the specification of object types, profi...
