Location models are data structures or knowledge bases used in Ubiquitous Computing for representing and reasoning about spatial relationships between so-called smart objects, i.e....
In this paper we propose a classification-based method towards the segmentation of diffusion tensor images. We use Support Vector Machines to classify diffusion tensors and we ex...
Unlike most existing work on traversable interfaces, we focus on the use of synthetic characters to accompany the user in Mixed Reality (MR) applications. We examine virtual compa...
We introduce a framework for supporting crowds of participants in collaborative virtual environments (CVEs). The framework is realised as an extension to our previous spatial mode...
Today, there is a huge amount of data gathered about the Earth, not only from new spatial information systems, but also from new and more sophisticated data collection technologie...
