The team at Rochester, which is led by Roger Easton, is concentrating on so-called multispectralanalysis, borrowing techniques that were developed for analysing satellite images of the earth.
Over the past decade Dr Obbink, Dr Kovalchuk and their team have both improved the hardware of multispectralanalysis (which was originally developed by America's space agency, NASA), and written more sophisticated algorithms to analyse what is seen.
