Mapping banana plants to facilitate plant health assessment


Date: 27/11/2014


A new mapping approach allows for better identification of banana plants that have been affected by Banana Bunchy Top Virus (genus: Babuvirus) that reduces plant growth and prevents banana production. Developed by Kasper Johansen of the Biophysical Remote Sensing Group, School of Geography, University of Queensland, Australia and colleagues, the approach is based on very high spatial resolution airborne orthophotos. Object-based image analysis is used to: (i) detect banana plants using edge and line detection approaches; (ii) produce accurate and realistic outlines around classified banana plants; and (iii) evaluate the mapping results.
