Studying insect vision allows significant insights into how visual systems operate which may hold important lessons for machine vision. Recent work suggests a level of sophistication in insect vision, depending upon experience, which was previously thought to require large mammalian brains. Bumblebees and honeybees see ultraviolet, blue and green ‘colours’, and process information with a brain containing less than 1 million neurons. The bee brain learns colour information differently depending upon the specific conditioning procedure, leading to long term colour memory and the development of attention-like processing. When bees learn fine colour discrimination tasks then speed-accuracy tradeoffs are observed both between individuals, and for groups learning tasks of different degrees of difficulty, suggesting high level ‘executive’ decision making within the bees’ brain for understanding the implications of different problem solving strategies. The bee brain is also able to bind colour information as a predictor of flower temperature, with important implications for what plant species perform best in different environments. Considering spatial vision, the insect visual system can learn to reliably recognise face stimuli using configural type processing, and learn complex rules governing relationships between different elemental features. This behavioural evidence suggests that relatively small brains can learn very complex tasks, and this may hold lessons for what can be achieved with machine vision into the future.
Assoc. Prof Dyer is based in the School of Media and Communication at RMIT as an ARC QII Fellow. He is also an Alexander von Humboldt Fellow (Germany). Completed PhD (2000) under Robin Williams and Bill Muntz at RMIT, and then completed several post doc positions (Cambridge University in the UK, La Trobe University, Monash University, Mainz and Wuerzburg Universities in Germany).
