Document Summary
Why is it so difficult to design a perceiving machine. The image cast on your retina is ambiguous. Inverse projection problem: the fact that an image on your retina can be created by many different objects. Information from a single view of an object can be ambiguous: humans solve this problem by moving to different viewpoints, and by making use of knowledge they have gained from past experiences. People easily understand that the part of an object that is covered continues to exist. People can detect objects that are not in sharp focus, such as faces. Another problem for a perception machine is objects are often viewing from different angles. This mean that the images of objects are continually changing depending on the angle from which they are viewed. Viewpoint invariance: ability to recognize objects seen from different viewpoints. Gestalt: a whole configuration that cannot be described merely as the sum of its parts.
