PS262 Chapter Notes - Chapter 5: Occipital Lobe, Likelihood Principle, Receptive Field
Document Summary
The fact that a particular image on the retina can be created by many different objects is called inverse projection problem. People are able to recognize objects that are not in sharp focus; despite the degraded nature of these images, people can often identify most of them whereas computers perform poorly on this task. Another problem facing any perception machine is that objects are often viewed from different angles therefore always changing depending on which angle they are viewed from. The ability to recognize an object seen from different view points is called viewpoint invariance. Gestalt psychologists means a whole configuration that cannot be described merely as the sum of its parts. The idea that perception is the result of adding up sensations was disputed and then the g psychologists instead presented the idea the whole differs from the sum of its parts.
