Object Representation

To recognize objects, one must have an internal representation of an object suitable for matching its features to image descriptions. There are several approaches to modeling, and this research uses a surface-based object representation distinguished by its use of shape segmentable surfaces organized in a subcomponent hierarchy. This approach provides the information needed to efficiently recognize and locate complicated articulated structures (like a robot) when using the input data described in Chapter 3.

This chapter also briefly describes the SMS modeling approach [70], whose development was based on experience with the IMAGINE I system.
