ABSTRACT.

Hyperspectral remote sensing is a unique image acquisition method for studying light response properties of different materials. Materials could be anything such as corals, seagrass, water, coral cores, rocks, leaf, pineapple, etc. The data generated is a 2D image of a scene with each pixel containing its corresponding reflected spectral property, essentially a multi-dimensional dataset.

Unlike conventional cameras that capture only three channels of colour information (namely, red, green and blue), hyperspectral imaging captures hundreds of channels of colour information which allows for a continuous band of spectral information to be measured across every pixel in the scene. This unique spectral profile is known as the material’s spectral signature. The materials spectral signature are like fingerprints, allowing us to study, classify and monitor materials through non-destructive means.

Coupled with drone capabilities (on demand use, medium range, customisable missions, etc), the information-rich spectra provide usefulness in a range of marine science applications, such as pre-bleaching indicators, coral reef health/diversity maps, water quality, change detection, seagrass monitoring, coastal monitoring, etc.

BIO.

Dr Jon Kok is a Research Scientist at the Australian Institute of Marine Science (AIMS) within the Technology Development Engineering team. He is currently developing and demonstrating the use of hyperspectral technology for a range of marine and coastal science applications, such as seagrass monitoring, water quality, shallow coral reef mapping, bleaching/stress studies, fluorescence properties of coral skeleton cores and corals, etc.

Other than hyperspectral technology, Jon is also familiar with autonomous systems in aerial drones, optimisation problems and algorithms (genetic algorithm, MOEA, etc), multi-objective optimisation problems and algorithms, artificial intelligence/machine learning, 3D printing, automated image processing methods, and snowboarding.

External visitors – wish to join us and connect to our seminars?
External parties may connect to the live seminar via *N SEBE VMP LES Seminars 52236958@deakin.edu.au [ID.36958] via the methods listed below:

• For external guests, you can connect as a web guest by clicking HERE. If using Chrome you it will prompt you to install the Cisco Jaba Plugin, then it will prompt you to download the extension which you will need to install. Once this has been installed, you will have a black screen with a call button. You will just need to click call and it should connect into the VMP.
• For Deakin staff and students, please join via Skype for Business (Lync) – if you have office installed you may already have Skype for business or Lync installed. You just need to look for it on the start menu. If you find it, you can log into skype using your Deakin email and password and then dial 36958.
• Could not log in? More info on how to connect is available HERE or HERE.
• From a mobile phone or landline: call +613 92517000, wait for the prompt, then enter the five digit VMP number (36958)
• Please note that connection is only available while a seminar is taking place.

As a courtesy, we request that when connecting to the seminar that you mute your microphone unless you are required to speak, this would ensure that the sound from the speaker to the audience is not disrupted by feedback from your microphone – thank you!
