Hyperspectral Imaging – An engineering tool for agricultural applications

A masterclass with Dr Seung-Chul Yoon, Research Electronics Engineer, Quality & Safety Assessment Research Unit, US Department of Agriculture and 2019 Institute of Advanced Studies Visiting Fellow.

As the world heads towards the year 2050, it faces the daunting challenge of producing 50% more food to feed the world population, on essentially no more resources. In recent times, it has become very clear that the efficiency gains required to meet this challenge can only come about by Engineering innovations in support of Agriculture. In acknowledgement of this fact UWA has taken a two-pronged approach. Firstly, the Faculty of Engineering and Mathematical Sciences has appointed two new staff members in support of setting up a new Masters program in Agricultural Engineering. Secondly, the UWA Institute of Agriculture has added a sixth major research theme, Engineering Innovations for Food Production to boost collaborative research between the fields of Agriculture and Engineering. Through these initiatives, UWA is placing itself in a very strong position to contribute to this global challenge.

Although the Engineering tool of Hyperspectral Imaging is gaining significant interest in a multitude of application areas including Agriculture, past applications of this tool has been limited by (1) computational power on readily available computing platforms, and (2) the size and cost of the imaging spectrometer instruments. However, over recent years, the development of smaller, lower cost spectrometers, and the availability of low-cost high-power computing platforms, have made hyperspectral imaging a very promising technology for a host of new applications. Especially without major barriers to entry, applications of hyperspectral imaging in Agriculture are growing fast.

This masterclass will explore the applications hyperspectral imaging as a powerful and versatile Engineering tool for serving Agricultural applications. The program will start with a detailed introduction to hyperspectral imaging and hyperspectral data analysis, tailored towards agricultural and biological engineers. Building upon this foundation, the presenter will then examine applications in food quality and safety, using case studies of the presenter’s work, in the areas of high-speed hyperspectral imaging, real-time machine vision, and microbial colony detection using hyperspectral imaging.

Dr Yoon is a Research Electronics Engineer in the Quality and Safety Assessment Research Unit at the US National Poultry Research Center, USDA-ARS, Athens, Georgia. He received his PhD in Electrical Engineering from University of Illinois at Urbana-Champaign and has over 20 years of R&D experience in developing machine vision and image processing algorithms, and over 15 years in hyperspectral imaging. At USDA-ARS, he has led the development of objective and rapid imaging technologies and systems to solve food safety and quality problems faced in the poultry and egg industry, such as faecal detection, pathogen detection, egg crack detection and woody breast detection. As an expert in high-speed hyperspectral imaging and real-time machine vision in food and agriculture, he has also led the development of real-time high-speed imaging systems capable of operating at commercial poultry processing line speeds.

This masterclass is presented by the UWA Institute of Advanced Studies, the UWA Institute of Agriculture, and the UWA Faculty of Engineering and Mathematical Sciences Advanced Sensing and Quantum Technologies (ASQT) Research Cluster.
