Personal profile

Research interests

Pattern recognition, computer vision and machine vision, artificial neural networks, machine learning and deep learning.  Applications in medical image analysis, malware detection, industrial inspection.

Research engagement

Len engages with industry in R&D for a variety applications of machine vision and machine learning.  Past projects include:

  • Recognition of targets in sonar images from autonomous underwater vehicles, with Defence Industry Network.
  • Recognition of radar signals with Defence Services Technology Group.
  • Locomotive pantograph inspection system (PanCam) with Aurizon Ltd.  The developed system has been deployed since 2007 for timely automated detection and reporting of pantograph damage and wear.
  • Biscuit bake inspection system with Arnott's Biscuits Ltd.  Combines colour-calibrated image analysis with machine learning to report bake colour quality.
  • Inspection of recycled glass colour purity with Visy Recycling.

Research student supervision

Len supervises PhD and MRes candidates in topics related to machine learning and image analysis.  He is currently supervising three PhD candidates.
