Many of us believe that our eyes work like a camera. That explanation may be simple, but it is not true. In fact, the eye works more like a sophisticated computer than a camera, recognizing objects by analyzing their features.
Visual images come through a blurry lens, pass through a web of blood vessels, and land on a shaking field of receptors in our eyes. Yet these images look like sharp images to us. In this class we will examine the stages of visual processing to understand how this happens. We will view interesting demonstrations of many of these stages of processing.
We will also learn about the errors that the visual system makes. These errors can result in some amazing optical illusions that we will show and come to understand.
