    Emerging computational multimedia tools and techniques promise powerful ways to organise, search and browse our ever-increasing multimedia contents by automating annotation and indexing, augmenting meta-data, understanding media contents, linking related pieces of information amongst them, and providing intriguing visualisation and exploration front-ends. Identifying real-world scenarios and designing interactive applications that leverage these developing multimedia technology is certainly an important research topic in itself but poses a number of challenges. In this talk, I will discuss and highlight some of these challenges in designing these novel applications by reflecting on my own design practice with a number of design examples

    Data Hiding and Its Applications

    Get PDF
    Data hiding techniques have been widely used to provide copyright protection, data integrity, covert communication, non-repudiation, and authentication, among other applications. In the context of the increased dissemination and distribution of multimedia content over the internet, data hiding methods, such as digital watermarking and steganography, are becoming increasingly relevant in providing multimedia security. The goal of this book is to focus on the improvement of data hiding algorithms and their different applications (both traditional and emerging), bringing together researchers and practitioners from different research fields, including data hiding, signal processing, cryptography, and information theory, among others

    REACTION 2013. 2nd International Workshop on Real-time and distributed computing in emerging applications. December 3rd, 2013, Vancouver, Canada.This paper summarizes key research findings in the area of real-time performance and predictabil- ity of multimedia applications in cloud infrastruc- tures, namely: outcomes of the IRMOS European Project, addressing predictability of standard vir- tualized infrastructures; Osprey, an Operating Sys- tem with a novel design suitable for a multitude of heterogeneous workloads including real-time soft- ware; MediaCloud, a novel run-time architecture for offering on-demand multimedia processing facil- ities with unprecedented dynamism and flexibility in resource management. The paper highlights key research challenges ad- dressed by these projects and shortly presents ad- ditional questions lying ahead in this area

    Beyond old economy - new economy dualism: Urban embeddedness of current innovation processes

    Current research on spatial embeddedness of the "New Economy" clearly demonstrates the use of diverse urban assets for the emerging branch. One frequent shortcoming is, however, a simplified idea of multimedia and internet enterprises as a counter-world to the traditional economy. We argue that the multitude of service companies dealing with Internet- and Multimedia applications should be considered as part of a comprehensive economic innovation process: Small, flexible and venturesome enterprises test new technology applications for economic purposes, sometimes successfully, sometimes without success. Future steps in this innovation process can be observed already: With increasing security about the economic use of new media technologies, more and more "traditional" enterprises integrate multimedia, internet and e-commerce in their daily work. What has been the domain of service enterprises will be more and more integrated in their former clients' corporations. Nevertheless, parts of multimedia and internet application might still require highly specialized skills, thus offering a basis for independent service companies even in the future. During the first phase of the innovation process, specific assets of the city have proved to be useful as research on urban and regional embeddedness of new media enterprises has shown. It seems as if traditional enterprises - instead of undertaking this step of innovation by themselves - have entrusted this trial-and-error process to an urban milieu, characterised by its creativity, its capacity to link diverse experts and its capacity to deal with uncertainty. Thus, an institutional choice has been made in order to externalize insecurity about the economic use of new technologies. The paper aims at linking the Schumpeterian innovation cycle approach and its application to regional development to the emergence of new media based industry and its links to the traditional economy. This approach should permit to go beyond the "new economy"-"old economy" dualism in order to reveal the underlying comprehensive innovative process. The centre of interest remains the urban and regional embeddedness of the current process, that is to say, the contribution of space to innovation. Based on case studies on the Hamburg metropolitan economy, its "new economy" and its increasing links between "new" and "old economy", we intend to illustrate the specific institutional form of the current innovation process in an urban context.

    Secure Communication in Wireless Multimedia Sensor Networks using Watermarking

    Wireless multimedia sensor networks (WMSNs) are an emerging type of sensor networks which contain sensor nodes equipped with microphones, cameras, and other sensors that producing multimedia content. These networks have the potential to enable a large class of applications ranging from military to modern healthcare. Since in WMSNs information is multimedia by nature and it uses wireless link as mode of communication so this posse?s serious security threat to this network. Thereby, the security mechanisms to protect WMSNs communication have found importance lately. However given the fact that WMSN nodes are resources constrained, so the traditionally intensive security algorithm is not well suited for WMSNs. Hence in this research, we aim to a develop lightweight digital watermarking enabled techniques as a security approach to ensure secure wireless communication. Finally aim is to provide a secure communication framework for WMSNs by developing new

    Artech 2008: proceedings of the 4th International Conference on Digital Arts

    ARTECH 2008 is the fourth international conference held in Portugal and Galicia on the topic of Digital Arts. It aims to promote contacts between Iberian and International contributors concerned with the conception, production and dissemination of Digital and Electronic Art. ARTECH brings the scientific, technological and artistic community together, promoting the interest in the digital culture and its intersection with art and technology as an important research field, a common space for discussion, an exchange of experiences, a forum for emerging digital artists and a way of understanding and appreciating new forms of cultural expression. Hosted by the Portuguese Catholic University’s School of Arts (UCP-EA) at the City of Porto, ARTCH 2008 falls in alignment with the main commitment of the Research Center for Science and Technology of the Arts (CITAR) to promote knowledge in the field of the Arts trough research and development within UCP-AE and together with the local and international community. The main areas proposed for the conference were related with sound, image, video, music, multimedia and other new media related topics, in the context of emerging practice of artistic creation. Although non exclusive, the main topics of the conference are usually: Art and Science; Audio-Visual and Multimedia Design; Creativity Theory; Electronic Music; Generative and Algorithmic Art; Interactive Systems for Artistic Applications; Media Art history; Mobile Multimedia; Net Art and Digital Culture; New Experiences with New Media and New Applications; Tangible and Gesture Interfaces; Technology in Art Education; Virtual Reality and Augmented Reality. The contribution from the international community was extremely gratifying, resulting in the submission of 79 original works (Long Papers, Short Papers and installation proposals) from 22 Countries. Our Scientific Committee reviewed these submissions thoroughly resulting in a 73% acceptance ratio of a diverse and promising body of work presented in this book of proceedings. This compilation of articles provides an overview of the state of the art as well as a glimpse of new tendencies in the field of Digital Arts, with special emphasis in the topics: Sound and Music Computing; Technology Mediated Dance; Collaborative Art Performance; Digital Narratives; Media Art and Creativity Theory; Interactive Art; Audiovisual and Multimedia Design.info:eu-repo/semantics/publishedVersio
