A part of the European cultural heritage thesaurus has already being offered as digital collections using various formats and thus there is a requirement for management, preservation and archiving of such digital assets as well...

The evolution of real time 3D graphics technologies in combination with high bandwidth Internet connections and modern Web browsers enable users to explore complex 3D scenes. As a rule, a virtual visitor has to manually explore the geometrically complex 3D model in order to discover points of interest. This manual exploration is a time consuming pr...

The paper presents definition extensions to MPEG-7 meta-data ones, mainly related to audio descriptors, introduced to e ciently describe traditional Greek music data features in order to further enable e cient music retrieval. A number of advanced content-based retrieval scenarios have been defined such as query by music rhythm, query by example an...

This paper presents the design and VLSI implementation, on a single chip, of a new real-time colour space converter, which performs the transformation of the RCB colour coordinates to the intensity, hue and saturation (IHS) colour space. This high speed VLSI chip is designed to work at 13.3 MHz and can process high resolution colour images of up to...
