To reduce the semantic gap between low-level visual features and the richness of human semantics, this paper proposes new algorithms, by virtue of the combined camera motion descri...
Abstract. This paper presents an approach on high-level feature detection using a region thesaurus. MPEG-7 features are locally extracted from segmented regions and for a large set...
Abstract. Multimodal and dialogue-based mobile interfaces to the Semantic Web offer access to complex knowledge and information structures. We explore more fine-grained co-ordina...
—Broadcasting of media events is a real-time action demanding reliable just in time decisions based on the current content of incoming video streams and the availability of backg...
—In this paper we present a scalable and distributed system for image retrieval based on visual features and annotated text. This system is the core of the SAPIR project. Its arc...
— Annotation of multimedia content with metadata is regarded as a key issue for efficiently handling such content. MPEG-7 is a major standard that has been developed for this rea...

—The vision of the Semantic Web is to lift the current Web into semantic repositories where heterogeneous data can be queried and different services can be mashed up. Ontology or...
Abstract—This paper presents an annotation tool for the manual and region-based annotation of still images. The selection of regions is achieved by navigating through a Partition...
