Robust Segmentation of Primitives from Range Data in the Presence of Geometric Degeneracy
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By David Marshall, Gabor Lukacs, Ralph Martin
Issue Date:March 2001
pp. 304-314
<p><b>Abstract</b>—This paper addresses a common problem in the segmentation of range images. We would like to identify and fit surfaces of known type wherever these are a good fit. This paper presents methods for the least-squares fittin...
 
Simulation of FLIR and LADAR Data Using Graphics Animation Software
Found in: Computer Graphics and Applications, Pacific Conference on
By Gavin Powell, Ralph Martin, David Marshall, Keith Markham
Issue Date:October 2000
pp. 126
This paper presents an implementation of Forward Looking Infrared (FLIR) and Laser Radar (LADAR) data simulation for use in developing a multi-sensor data-fusion automated target recognition (ATR) system. Using commercial models and software we can create ...
 
Merging and Splitting Eigenspace Models
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Peter Hall, David Marshall, Ralph Martin
Issue Date:September 2000
pp. 1042-1049
<p><b>Abstract</b>—We present new deterministic methods that given two eigenspace models—each representing a set of <tmath>$n$</tmath>-dimensional observations—will: 1) merge the models to yield a representation of the union o...
 
Vocal and facial trustworthiness of talking heads
Found in: Proceedings of the 3rd Symposium on Facial Analysis and Animation (FAA '12)
By Andrew J. Aubrey, Antony S. R. Manstead, Arvid Kappas, David Marshall, Elena Tsankova, Eva G. Krumhuber, Guido Möllering, Paul L. Rosin
Issue Date:September 2012
pp. 1-1
Trust is a key aspect to human communication due to its link to co-operation and survival. Recent research by [Ballew and Todorov 2007] has shown that humans can generate an initial trustworthiness judgement based on facial features within 100ms. However, ...
     
Comparing feature-based metrics for facial dynamics analysis
Found in: Proceedings of the ACM/SSPNET 2nd International Symposium on Facial Analysis and Animation (FAA '10)
By Andrew J. Aubrey, David Marshall, Gary K. L. Tam, Hui Fang, Min Chen, Paul L. Rosin, Phil W. Grant
Issue Date:October 2010
pp. 23-23
The automatic analysis and classification of facial expressions is a challenging problem. It has been an active area of research for many years, with a range of applications, including affective computing, human computer interaction and lipreading. Althoug...
     
Comparison of techniques for audio driven facial animation
Found in: Proceedings of the ACM/SSPNET 2nd International Symposium on Facial Analysis and Animation (FAA '10)
By Andrew Aubrey, Benjamin Havell, David Marshall, Paul Rosin, Saeid Sanei, Yulia Hicks
Issue Date:October 2010
pp. 22-22
A fast and accurate Audio Driven Facial Animation system would have many applications such as video games and television, where animation is not currently feasible due to cost or time restraints.
     
Behaviour transfer between expressive talking heads
Found in: Proceedings of the ACM/SSPNET 2nd International Symposium on Facial Analysis and Animation (FAA '10)
By Andrew Aubrey, David Marshall, Paul Rosin
Issue Date:October 2010
pp. 9-9
Performance driven animation (also called expression mapping) is an important area of research in computer graphics. The technique relies on using an input face to animate either a computer generated face or a real face [Cosker et al. 2008; Vlasic et al. 2...
     
Towards perceptually realistic talking heads: models, methods and McGurk
Found in: Proceedings of the 1st Symposium on Applied perception in graphics and visualization (APGV '04)
By Darren Cosker, David Marshall, Paul. L. Rosin, Simon Rushton, Susan Paddock
Issue Date:August 2004
pp. 151-157
Motivated by the need for an informative, unbiased and quantitative perceptual method for the development and evaluation of a talking head we are developing, we propose a new test based on the "McGurk Effect". Our approach helps to identify strengths and w...
     
Using the Internet to teach the Internet
Found in: Proceedings of the 6th annual conference on the teaching of computing and the 3rd annual conference on Integrating technology into computer science education: Changing the delivery of computer science education (ITiCSE '98)
By David Marshall
Issue Date:August 1998
pp. 153
In recent years a methodology for Courseware design together with a number of Web based courses have been developed at Cardiff. A variety of disciplines have benefited notably C programming, X Window/Motif programming, Computer Vision, Image Processing, Co...
