An interesting blog post on optical illusions over at brain blogger. I think that computer vision could benefit a lot from studying optical illusions. The brain uses a lot of tricks in order to interpret the visual information we receive from our eyes and optical illusions occur when these tricks go wrong.

The thing is that these tricks are obviously good tricks as they do work most of the time, and these pathalogical cases where they go wrong, can give us some insight in to how the visual system does what it does.
