Document Summary
It is necessary to go beyond the pattern of light and dark that a scene creates on the retina to determine what is out there . The perceptual system is not concerned with determining an object"s image on the retina. It starts with the image on the retina, and its job is to determine the object out there that created the image. The task for determining the object responsible for a particular image on the retina is called the inverse projection problem. It involves starting with the retinal image and extending rays out from the eye. The ability to recognize an object seen from different viewpoints is called viewpoint variance. This enables people to tell whether faces seen from different angles are the same person, but this task is difficult computers. Perceptual organization: the process by which elements in the environment become perceptually grouped to create our perception of objects.
