Analyzing data streams using a dynamic compact stream pattern algorithm (2019)
Journal Article
Oyewale, A., Hughes, C., & Saraee, M. (2019). Analyzing data streams using a dynamic compact stream pattern algorithm

A growing number of applications that generate massive streams of data need intelligent data
processing and online analysis. Data & Knowledge Engineering (DKE) has been known to stimulate the
exchange of ideas and interaction between these two rela... Read More about Analyzing data streams using a dynamic compact stream pattern algorithm.

Understanding the diverse needs of subtitle users in a rapidly evolving media landscape (2017)
Journal Article
Armstrong, M., Brown, A., Crabb, M., Hughes, C., Jones, R., & Sandford, J. (2017). Understanding the diverse needs of subtitle users in a rapidly evolving media landscape. SMPTE motion imaging journal, 125(9), 33-41. https://doi.org/10.5594/JMI.2016.2614919

Audiences are increasingly using services, such as video on demand and the Web, to watch television programs. Broadcasters need to make subtitles available across all these new platforms. These platforms also create new design opportunities for subti... Read More about Understanding the diverse needs of subtitle users in a rapidly evolving media landscape.

Storyboarding for visual analytics (2013)
Journal Article
Walker, R., Cenydd, L., Pop, S., Miles, H., Hughes, C., Teahan, W., & Roberts, J. (2015). Storyboarding for visual analytics. Information Visualization, 14(1), 27-50. https://doi.org/10.1177/1473871613487089

Analysts wish to explore different hypotheses, organize their thoughts into visual narratives and present their
findings. Some developers have used algorithms to ascertain key events from their data, while others have
visualized different states of... Read More about Storyboarding for visual analytics.

A directed particle system for optimised visualization of blood flow in complex networks (2013)
Journal Article
Pop, S., Hughes, C., Ap Cenydd, L., & John, N. (2013). A directed particle system for optimised visualization of blood flow in complex networks. https://doi.org/10.3233/978-1-61499-209-7-330

This paper introduces a novel technique for the visualization of blood (or other fluid) flowing through a complex 3D network of vessels. The Directed Particle System (DPS) approach is loosely based on the computer graphics concept of flocking agents....

A model for flexible tools used in minimally invasive medical virtual environments (2011)
Journal Article
Soler, F., Luzon, M., Pop, S., Hughes, C., John, N., & Torres, J. (2011). A model for flexible tools used in minimally invasive medical virtual environments. https://doi.org/10.3233/978-1-60750-706-2-594

Within the limits of current technology, many applications of a virtual environment will trade-off accuracy for speed. This is not an acceptable compromise in a medical training application where both are essential. Efficient algorithms must therefor...
