A GPU based, projective multi-texturing approach to reconstructing the 3D human form for application in tele-presence
Presentation / Conference
Aspin, R., & Roberts, D. A GPU based, projective multi-texturing approach to reconstructing the 3D human form for application in tele-presence. Presented at ACM 2011 conference on Computer supported cooperative work, Hangzhou, China

This paper reports a GPU based, projective texturing approach to reconstructing the human form, from multiple images, at a quality and frame rate close to high end video conferencing. The ultimate aim is to support spatially grounded, non-verbal comm...

MediVol: An initial study into real-time interactive 3D visualisation of soft tissue pathologies
Presentation / Conference
Aspin, R., Smith, M., Hutchinson, C., & Funk, L. MediVol: An initial study into real-time interactive 3D visualisation of soft tissue pathologies. Presented at 12th IEEE/ACM International Symposium on Distributed Simulation and Real-Time Applications, Vancouver, BC

None-invasive scanning technologies, such as MRI, have greatly enhanced our ability to ‘image’ the internal body, however the resultant visualisation is often difficult to comprehend due to both inadequacies in the scanning process and sub-optimal ap...

Synchronization of images from multiple cameras to reconstruct a moving human
Presentation / Conference
Moore, C., Duckworth, T., Aspin, R., & Roberts, D. Synchronization of images from multiple cameras to reconstruct a moving human. Presented at Distributed Simulation and Real Time Applications (DS-RT), 2010 IEEE/ACM 14th International Symposium on, Fairfax, VA

What level of synchronization is necessary between images from multiple cameras in order to realistically reconstruct a moving human in 3D? Live reconstruction of the human form, from cameras surrounding the subject, could bridge the gap between vide...

An exploration of non-tessellated 3D space carving for real-time 3D reconstruction of a person through a simulated process
Presentation / Conference
Aspin, R., & Roberts, D. An exploration of non-tessellated 3D space carving for real-time 3D reconstruction of a person through a simulated process. Presented at Visual Media Production (CVMP), 2010 Conference on, London

Real-time 3D reconstruction of people promises to combine the winning characteristics of video conferencing and immersive collaborative virtual environments. However, it remains difficult to obtain a reconstruction of a person with recognisable facia...

Spatial soliton refraction at cubic-quintic material interfaces
Presentation / Conference
McCoy, E., Christian, J., & McDonald, G. Spatial soliton refraction at cubic-quintic material interfaces. Poster presented at Salford Postgraduate Annual Research Conference (SPARC 11), University of Salford, Greater Manchester, UK

In their most general form, wave–interface problems are inherently angular in nature. For instance, the interaction between light waves and material boundaries essentially defines the entire field of optics [1]. The seminal works of Aceves et al. [2,...

Families of two-colour Helmholtz spatial solitons
Presentation / Conference
Bostock, C., Christian, J., & McDonald, G. Families of two-colour Helmholtz spatial solitons. Poster presented at Salford Postgraduate Annual Research Conference (SPARC 11), University of Salford, Greater Manchester, UK

Multi-colour spatial solitons comprise localized optical components at distinct temporal frequencies [1]. The
components (which may be bright-like and dark-like) tend to overlap in space, thereby allowing the interplay
between linear spreading (dif... Read More about Families of two-colour Helmholtz spatial solitons.

From Turing instability to fractals
Presentation / Conference
Huang, J., Christian, J., McDonald, G., Jahanpanah, J., & Chamorro-Posada, P. From Turing instability to fractals. Presented at Nonlinear Photonics Topical Meeting, Quebec City, Canada

Complexity focuses on commonality across subject areas and forms a natural platform for multidisciplinary activities. Typical generic signatures of complexity include: (i) spontaneous occurrence of simple patterns (e.g. stripes, squares, hexagons) em... Read More about From Turing instability to fractals.

Helmholtz solitons: a new angle in nonlinear optics
Presentation / Conference
Christian, J., McDonald, G., Chamorro-Posada, P., & Sanchez-Curto, J. Helmholtz solitons: a new angle in nonlinear optics. Poster presented at Nonlinear Photonics Topical Meeting, Quebec City, Canada

We rigorously show that nonparaxial optical beams are not necessarily ultranarrow [1-3]. While existing paraxial
models constrain considerations of broad beams to vanishingly-small propagation angles relative to the longitudinal (i.e. z) direction,... Read More about Helmholtz solitons: a new angle in nonlinear optics.

Helmholtz solitons: a new angle in nonlinear science
Presentation / Conference
Chamorro-Posada, P., McDonald, G., Sanchez-Curto, J., & Christian, J. Helmholtz solitons: a new angle in nonlinear science. Presented at Nonlinear Evolution Equations and Dynamical Systems (NEEDS), L’Ametlla de Mar, Spain

The ubiquitous nonlinear SchrÄodinger (NLS) equation models soliton propagation in many di®erent scenarios. In a nutshell, the NLS equation describes the slow modulation of the envelope of a linear wave when propagating in a weakly nonlinear medium....

Peristaltic flow of non-Newtonian, compressible fluid with non-zero boundary slip
Presentation / Conference
Tsiklauri, D., Christian, J., & McDonald, G. Peristaltic flow of non-Newtonian, compressible fluid with non-zero boundary slip. Poster presented at Materials Congress: Institute of Materials, Minerals, and Mining (IoM3), London, UK

In Tsiklauri & Beresnev, Phys Rev E 64, 036303 (2001), we investigated new phenomena brought about into the classic peristaltic mechanism by the inclusion of non-Newtonian effects based on the model of a Maxwell fluid. In Tsiklauri, J Acoust Soc Am 1... Read More about Peristaltic flow of non-Newtonian, compressible fluid with non-zero boundary slip.
