No doubt, the performance of a Content-Based Image Retrieval (CBIR) system depends on a) how efficient the image visual content is represented and b) the degree of importance, which is assigned to each content-descriptor. In the first case, efficient visual representation is achieved, apart from the extraction of appropriate descriptors, through a proper organization of them [1]. The second cas...

OBJECTIVE The aim of this study is to examine the extent to which functional, interactive and critical health literacy are associated with patients' perceived control over care and frequency of GP visits. METHODS Data from the Dutch 'National Panel of People with Chronic Illness or Disability' was used (N=2508). Health literacy was assessed by the Functional, Communicative and Critical Health...

This paper is an outgrowth of the filings in the FCC's broadband openness proceeding that focused on the issue of networks neutrality. Newly available data confirm that competition in the broadband access marketplace is limited. Wireless broadband access services are unlikely to act as effective economic substitutes for wireline broadband access services and instead are likely to act as a compl...

An interactive system for content-based retrieval in a pictorial database using color distribution features is discussed. Images are internally represented and indexed by a set of histograms reflecting homogeneous chromatic properties of image structure and also including color-induced geometric features. User query images are interactively composed through a graphic environment featuring color...

Digital television is a new and interesting platform for developing multimedia services. The MELISA platform aims at cross-media broadcasting over digital television and 3G mobile networks. The platform provides presentation of interactive video content, advertisement and gaming. The devices targeted by these services are Set-Top Boxes and Portable Digital Assistants. A new service, in combinat...

This paper addresses the dual problem of audio coding for compression and retrieval. Because of the sheer volume of multimedia data, much research effort has focused on coding techniques for the compression of this data. However, being able to store large amounts of data in a compact fashion has limited application if there is no meaningful way to access and interact with them. Traditionally, t...

Digital broadcasting enables interactive TV, which presents new challenges for interactive content creation. Besides the technology for streaming and viewing, tools and systems are under development that extend traditional TV studios with virtual set environments. This presentation reviews current technology and describes the requirements for such systems. Interoperability over the production, ...

CindyJS is a framework for creating interactive (mathematical) content for the web. The plugin CindyGL extends this framework and leverages WebGL for parallelized computations. CindyGL provides access to the GPU fragment shader for CindyJS. Among other tasks, the plugin CindyGL is used for real-time colorplots. We introduce the main principles, concepts and application of CindyGL and describe t...
