The availability of metadata about the semantics of information in multimedia documents is crucial for building semantic applications that offer convenient access to relevant information and services. In this work, we present a novel approach for the automatic generation of rich semantic metadata based on surface-level information. For the extraction of the required surface-level information st...

In this paper, we propose a systematic solution to the problem of scheduling delay-sensitive media data for transmission over time-varying wireless channels. We first formulate the dynamic scheduling problem as a Markov decision process (MDP) that explicitly considers the users’ heterogeneous multimedia data characteristics (e.g. delay deadlines, distortion impacts and dependencies etc.) and ti...

This paper describes how the multimedia mark-up languages SMIL and HTML+TIME were used to publish three types of online presentations of multi-modal artwork by mental health service users. This technology has the potential to bring the work of artists working with mental health services to a wider audience, at low cost, with fuller participation and also offers a number of new creative possibil...

File carving is a recovery technique that recovers files based on information about their structure and content without matching file system information. As files can be recovered from their content and/or file structure this technique is indispensable during digital forensics investigations. So far many approaches for the recovery of digital images have been proposed. The main contribution of ...

Multimedia information retrieval systems design is currently considered a complex task since it requires an understanding of users specific way of searching, processing and using data conveyed by different media (texts, images, videos, sounds etc.). In this work we first discuss the state of the art of research in the field of textual and visual information retrieval approaching its problems fr...

Interactive Multimedia Installations (IMIs) are invaluable for the history of art and culture, for media technology and for other disciplines involved in the scientific research and the areas of application. Despite their importance, Interactive Multimedia Installations show some weaknesses that threaten their chance to be preserved long enough to be studied or replicated: (1) they show a compl...

Art, music, and science come together as computer musicians and computer scientists collaborate to create EyeMusic, a system for composing and performing eyecontrolled musical and multimedia compositions. In EyeMusic, an eye-tracking device communicates with a musical and multimedia authoring environment to enable composers and artists to sonify and visualize eye movement data. During a live pe...

This paper outlines the design and evaluation of the Digital Classroom Application Framework (DeCAF). DeCAF is designed to provide an environment upon which multimedia applications for the classroom can be developed and evaluated. With the inclusion of multimedia in the modern digital classroom comes new paradigms for teaching. Also, the combination of the Internet and multimedia allow digital ...

Hashing has been widely applied to large-scale multimedia retrieval due to the storage and retrieval efficiency. Cross-modal hashing enables efficient retrieval from database of one modality in response to a query of another modality. Existing work on cross-modal hashing assumes heterogeneous relationship across modalities for hash function learning. In this paper, we relax the strong assumptio...

Multimedia data is rapidly gaining importance along with recent developments such as the increasing deployment of surveillance cameras in public locations. In a few years time, analyzing the content of multimedia data will be a problem of phenomenal proportions, as digital video may produce data at rates beyond 100 Mb/s, and multimedia archives steadily run into Petabytes of storage space. Cons...
