A MedTech West seminar – Reflections on natural and artificial vision

Human beings and machines are good at different tasks. As humans we still have the upper hand when it comes to global, approximate judgements. This is true also for perception. A human can often quickly segment a scene into its principal objects where the machine fails or takes very long time to achieve the task. Part of the explanation is probably that human perception uses analysis-by-synthesis in combination with Hebbian pattern completion. The perceptual systems actively search for familiar objects and recognize them even if the match is only partial. However, a more important explanation may be that objects are recognized well before their contours are. Objects are first seen as coloured, more or less homogeneous, areas with very vague borders. Then their details including their exact contours are analyzed, but only if there is a need for it. This kind of theory has its origin in Gestalt psychological theory (not to be confused with Gestalt therapy, which has little to do with Gestalt theory proper). Helge Malmgren´s short speech will outline some basic principles of Gestalt psychology, which afterwards can be discussed in terms of the relevance of them for artificial vision.

Helge Malmgren is a PhD, MD, senior professor in theoretical philosophy at the University of Gothenburg.
