Peter is a member of the Data Analytics, Fusion & Technology group within the CET.
Peter completed a Bachelor of Engineering in Mechanical Engineering at the University of Western Australia in 1981. This was followed by a Master of Engineering Science in the area of kinematic control of robot arms in 1984, also at UWA. His PhD, completed in 1996, was in computer vision. This work studied the construction of invariant low-level image measures from local phase information.
From 1984 to 1991 Peter was a research engineer with the Automated Sheep Shearing Project in the Department of Mechanical Engineering at UWA. During this time he was responsible for a number of areas in the project including surface modelling techniques, robot control software, and the development of a machine vision system for automated measurement of sheep. It was here that he developed his interest in computer vision.
In 1991 Peter joined the School of Computer Science & Software Engineering at The University of Western Australia. During this time he was responsible for the undergraduate teaching of computer vision and helped coordinate the computer vision research group within the school. It was around this time that his first contact with CET was made through interactions with Prof. Mike Dentith, Dr Carl Knox-Robinson and Dr Steve Gardoll. Some preliminary exploration ofthe application of computer vision techniques to the analysis of geological and geophysical images was made through student projects. These included the 3D modelling of ore bodies, image texture analysis, and lithological boundary shape analysis.
Peter left the School of Computer Science & Software Engineering in 2007 but maintained a link with the School via an adjunct position. His informal interaction with CET also continued, working with Assoc/Prof. Eun-Jung Holden and Prof. Mike Dentith. Eventually this relationship was formalised with a part-time appointment to CET within the Geophysics and Image Analysis group in 2010.
Peter has had visiting positions at The Stanford Research Institute Robotics Research Group as an International Fellow; The Department of Engineering Science, Oxford University with the Robotics Group as a visiting scholar; and INRIA Sophia-Antipolis, France with the ROBOTVIS group under a French Government Fellowship. He has also spent periods as a visiting academic at The Department of Electrical and Computer Engineering, University of Canterbury, NZ; The Department of Systems Engineering, ANU; and the School of Computer Science, University ofAdelaide.
Peter's research interests are mostly in low-level computer vision. Much of this work has concentrated on using local phase information in images to construct invariant quantities for feature detection,symmetry/asymmetry analysis, texture analysis, and feature matching. Some of these techniques have been commercialised through the CET Grid Analysis and the CET Porphyry Detection extensions for Geosoft Oasis Montaj.
Peter also has interests in photogrammetry and 3D reconstruction, forensic image processing and biometrics. A large collection of his software is available at his website MATLAB and Octave Functions for Computer Vision and Image Processing.
