This paper is partly a response to the ongoing debate in the game world about whether games can be art, and partly an excerpt from my Ph.D. research. I aim to offer some insights in the cognitive experiences gamers have while playing hopefully useful to both designers and scholars. I will argue that an art experience is a particular kind of cognitive experience, namely a distinctive type of ima...

This paper addresses the problem of synthesising animations from video clips; in particular emphasising the motion of tracked objects. We introduce “dynamic cues” as a class of motion emphasis cue, encompassing traditional animation techniques such as anticipation and exaggeration. We present methods for automatically synthesising such cues within video premised upon the recovery of articulated...

Over the past few years, face recognition has gained many interests. Face recognition has become a popular area of research in computer vision and pattern recognition. The problem attracts researchers from different disciplines such as image processing, pattern recognition, neural networks, computer vision, and computer graphics (Zhao, Chellappa, Rosenfeld & Phillips, 2003). Face recognition is...

Video and networking technologies have advanced such that posting and viewing video online is practical. Everyday people now post video online to communicate asynchronously with remote audiences. This paper explores the forms in which people communicate on the popular video sharing website YouTube. It also examines whether end-user video creators on YouTube use plot-based storytelling as a comm...

This paper proposes a new approach to conceptualizing digital and media art forms. This theoretical approach will be explored through issues raised in the process of creating a formal declarative model for digital and media art. This methodology of implementing theory as a way of exploring and testing it is intended to mirror the practices of both art making and computer processing. In these pr...

We present the video about assisting anti-retroviral therapy (ART) by an apt laboratory service - representing a South-African role model for economical large scale diagnostic testing. In the low-income countries inexpensive ART has transformed the prospects for the survival of HIV seropositive patients but there are doubts whether there is a need for the laboratory monitoring of ART and at wha...

Learning video concept detectors automatically from the big but noisy web data with no additional manual annotations is a novel but challenging area in the multimedia and the machine learning community. A considerable amount of videos on the web are associated with rich but noisy contextual information, such as the title, which provides weak annotations or labels about the video content. To lev...

We introduce an efficient and flexible framework for temporal filtering in wavelet based scalable video codecs called unconstrained motion compensated temporal filtering (UMCTF). UMCTF allows for the use of different filters and temporal decomposition structures through a set of controlling parameters that may be easily modified during the coding process, at different granularities and levels. ...

The explosion of multimedia digital content and the development of technologies that go beyond traditional broadcast and TV have rendered access to such content important for all end-users of these technologies. While originally developed for providing access to multimedia digital libraries, video search technologies assume now a more demanding role. In this paper, we attempt to shed light onto...

H.264/MPEG-4 AVC is the latest international video coding standard. It was jointly developed by the Video Coding Experts Group (VCEG) of the ITU-T and the Moving Picture Experts Group (MPEG) of ISO/IEC. It uses state-of-the-art coding tools and provides enhanced coding efficiency for a wide range of applications, including video telephony, video conferencing, TV, storage (DVD and/or hard disk b...
