Paper Abstract

A number of objects in the real world can be described as surfaces of revolution. These are a particular type of generalized cylinder with a straight axis whose 3-D shape is formed by rotating a 2-D plane about the axis. Examples of such objects are vases, many chess pieces, light bulbs, table lamps, etc. This paper describes a number of techniques that can be used to recognize this class of object in a typical cluttered scene under perspective projection. Use is made of the symmetry of the occluding boundary, perceptual grouping of ellipses, 3-D models and the hypothesis that an ellipse is a circle in the real world.
