    Cross-layer designs are becoming more and more attractive within the multimedia community since multiple-play services pave their way towards consumer markets enabling mobility in various aspects. However, cross-layer designs so far have mainly focused on performance issues and do not provide much support in terms of interoperability which is a requirement for services envisaged as part of the Fix...

    Video content remixing - generic or personalised - is available on the Web in various forms. Most platforms target at users uploading and rearranging content, and sharing it with the community. Although several implementations exist, to the best of our knowledge no solution uses metadata to its full extent to, e.g., dynamically render a video stream. With the research presented in this paper, we p... View full abstract»

    The subjective user satisfaction related to viewing a video on a resource constrained mobile device is modeled by using a utility function. The resulting models account for different video content characteristics and varying hardware capabilities of the viewing device. The user satisfaction is divided into two independent components, namely the temporal and the spatial satisfaction. Subjective vid... View full abstract»

    An approach for quality-of-service based replica management in a proxy-to-proxy network is presented. Management decisions are based on a metrics called replication affinity. Replication affinity combines two other affinity metrics we call (1) placement affinity and (2) reallocation affinity. Placement affinity is used to find the best location to enable QoS based media delivery to future clients.... View full abstract»

    The content-based image retrieval (CBIR) methods have been applied to medical field to aid diagnosis and other medical processes for a relatively long time. This type of systems, with the growth of digital medical image databases, sometimes does not provide information tailored to the end user requirements. Typically there is a semantic gap between the low-level features extracted form the images ... View full abstract»

    The World Wide Web can be accessed through a number of different devices, each having its own capabilities and limitations. Additionally, the content of the Web is increasing tremendously in size and variety. Yet, many devices do not embed support for all types of media and formats. Therefore, in order to provide as much information as possible to all kind of devices, media items have to be adapte... View full abstract»

    While the extraction of low level multimedia features has been largely studied, the automatic extraction of high level descriptions is still an open research field. Moreover, as semantic Web languages, which are based on description logics, are conceived for describing all kinds of resources, specific extensions of semantic languages for describing multimedia resources are needed. Descriptors offe... View full abstract»

    Effective management and exploitation of multimedia documents requires extraction of the underlying semantics. Multimedia analysis algorithms can produce fairly rich but imprecise information about a multimedia document. In this paper, a multimedia reasoning architecture is presented using the fuzzy extension of expressive SHIN, f-SHIN. First a segmentation algorithm generates a set of over-segmen...

    The contemporary information infrastructure gives way to a massive offer of news sources and subsequently news contents. Finding such sources and filtering relevant news according to personal preferences is a time-consuming task in the daily effort to stay informed. Moreover many of these sources are not accessible when spare time to read news is available, especially while being en-route. Persona... View full abstract»

    In a series of user studies the aceMedia project investigated user needs and context of use concerning an innovative multimedia management system. Among a multitude of findings, we unexpectedly found users very sceptic about personalization. We report on user feedback concerning personalization, identify relevant user requirements, and draw conclusions in which context of use personalization will ... View full abstract»

    This paper presents a distributed client-server architecture for the personalized delivery of textual news content to mobile users. The user profile is distributed across client and server, enabling a high-level filtering of available content on the server, followed by matching of detailed user preferences on the handset. The high-level user preferences are stored in a skeleton profile on the serv... View full abstract»

    This paper presents a new algorithm that allows us to generate 3D geometry from a single monocular image through the optimisation of an objective function. Weighted smoothness constraint is designed and added to the objective function to provide adequate smooth restraints in accordance with local image gradients. By using wavelet, the objective function is minimised to recover geometry from the in... View full abstract»

    Spatial relations between image regions are used in this paper for image classification in a rule-based fashion. In the particular case where image regions correspond to semantically interpretable objects the rules provide the means for justifying classification in a human-familiar manner. In the work presented here instances of particular object classes are detected combining bottom-up (learnable... View full abstract»

    This paper presents an approach for efficient keyframe extraction, using local semantics in form of a region thesaurus. More specifically, certain MPEG-7 color and texture features are locally extracted from keyframe regions. Then, using a hierarchical clustering approach a local region thesaurus is constructed to facilitate the description of each frame in terms of higher semantic features. The t... View full abstract»

    Existing multimedia information retrieval systems provide users with insufficient support for efficient searching for and browsing in multimedia content. Several possible solutions were proposed, such as using faceted metadata search or semantic clusters of search results. We describe the possibilities of using enhanced faceted navigation with support for personalization, collaboration and Semanti... View full abstract»
