Abstract
Vision is, without doubt, our sense par excellence. That the eye and the visual pathways could have evolved simply as a result of natural selection was a concept that taxed even Darwin’s imagination as he espoused his trail-blazing theory of evolution in The origin of species (Darwin 1859). It is no surprise, then, that the task of developing artificial systems that ‘see’ and ‘perceive’ the world in the way we do, is not a trivial one.
