Edge detection crucial to eyesight

Description

In a major advance in understanding how our eyesight works, Australian scientists have shown that birds' amazing flight and landing precision relies on their ability to detect edges.

The research suggests that edge detection is crucial in helping all animals, including humans, move around safely, and may be more important than our ability to see colour.

The study by the The University of Queensland and the Vision Centre and found that budgerigars ignore colour and look for the edge of an object in order to ensure a smooth landing, and will be published in PLoS ONE on 7 October, 2009.
