Topics in 3D Computer Vision at UWA

The objective of this talk will be to provide a brief introduction to the area of 3D computer vision and some of the related work that has been done in the School of Computer Science and Software Engineering at the University of Western Australia. It will briefly include 3D surface acquisition using short and long laser scanners and a home-built structured light system. Illustrations showing 3D surface objects and faces and the sort of pre-processing required to clean the data will be given . A couple of applications and their motivations will be briefly described including 3D object recognition and 3D face biometrics. The talk will then describe in a bit more details our 3D object recognition work followed by our 3D face biometrics work. With respect to 3D object recognition, a very brief description of surface representations including our tensor representation will be provided. We will then describe how this representation has been used for surface registration and 3D reconstruction. Examples of 3D reconstructed models will be shown. Illustrations on how our tensor representation and the use of a multiview correspondence algorithm using a hash table have been used for 3D object recognition in presence of occlusion, clutter. A comparative performance with other techniques will finally be provided. Some of the work in the area of 3D biometrics will also be briefly covered.

Short Biography: Mohammed Bennamoun received his M.Sc. from Queen's University, Kingston, Canada in the area of Control Theory, and his PhD from Queen's /Q.U.T in Brisbane, Australia in the area of Computer Vision. He lectured Robotics at Queen's, and then joined QUT in 1993 as an Associate Lecturer. He then became a Lecturer in 1996 and a Senior Lecturer in 1998 at QUT. He was also the Director of a research Centre from 1998-2002. In Jan. 2003, he joined the Department of Computer Science and Software Engineering at The University of Western Australia (UWA) as an Associate Professor and was promoted to Professor in 2007. He has been the Head of the School of Computer Science and Software Engineering at UWA since February 2007. He was an Erasmus Mundus Scholar and Visiting Professor in 2006 at the University of Edinburgh. He was also Visiting Professor at the Helsinki University of Technology in 2006, the University of Bourgogne and Paris 13 in France in 2002-2003. He is the co-author of the book `Object Recognition: Fundamentals and Case Studies', Springer-Verlag, 2001. He won the "Best Supervisor of the Year" Award at QUT. He also received an award for research supervision at UWA in 2008. He published over 120 journal and conference publications. He served as a guest editor for a couple of special issues in International journals, such as the International Journal of Pattern Recognition and Artificial Intelligence (IJPRAI). He was selected to give conference tutorials at the European Conference on Computer Vision (ECCV) and the International Conference on Acoustics Speech and Signal Processing (IEEE ICASSP). He organized several special sessions for conferences; including a special session for the IEEE International Conference in Image Processing (http://www.icip2004.org/ IEEE ICIP). He was on the program committee of many conferences e.g. 3D Digital Imaging and Modeling (3DIM) and the International Conference on Computer Vision. He also contributed in the organisation of many local and international conferences. His areas of interest include control theory, robotics, obstacle avoidance, object recognition, artificial neural networks, signal/image processing and computer vision (particularly 3D).
