Title: Bayesian Surface Warping Approach for Rectifying Geological Boundaries: Developing Spatial Algorithms and Systems for Mining in the Pilbara

This seminar coincides with the 13th anniversary of RTCMA. To mark this occasion, we will tell a mining story (describe iron ore mining operations in the Pilbara) and highlight RTCMA’s recent and ongoing contributions. The talk itself is divided into two parts. The first part lays a foundation for understanding the problems, inter-connections, and RTCMA’s involvement in this space. The second part is structured around a case study which focuses on developing spatial algorithms and systems for geology modelling. For the component considered, the objective is to rectify inaccuracies in the geological boundary representation by manipulating mesh surfaces using geochemical observations.

Raymond Leung received his PhD from UNSW – where he conducted research in scalable video compression and perceptual optimisation as a postdoc. Following graduation, he joined Motorola and worked on implementing the JPEG2000 image coding standard (ISO/IEC 15444). During a brief stint at NICTA, he developed an interest in machine learning and computer vision. He joined ACFR-RTCMA in 2011 and has since worked on different projects as a Senior Software Engineer. He also publishes in journals from time to time.

Alexander Lowe received his PhD from Curtin University where he developed instrumentation and signal processing techniques for corrosion measurement. In his first industry role he developed instrumentation and control systems for CustomVis’s Pulzar Z1 solid state laser eye surgery machine. Following that he took a role at CEA technologies in Canberra where he developed RF electronics for phased array radars. For the past 13 years he has been working with RTCMA, initially helping to develop the control software for automated drills before moving on to develop software for various projects including automated survey vehicles, hyperspectral imaging and orebody estimation. He was appointed Lead Technical Engineer in 2015. Alex has extensive experience in project management, innovation and technology transfer in industry-research partnerships. He is recognised as an inventor of surface warping in an international patent.
