Digital Objects, Image Transformations, and Reasoning Process

In Chap. 2, the shape classes used for the object description in terms of the perceptual categories are described. The perceived object has to be fitted into one of the shape categories during the reasoning process. It is assumed that visual object is extracted from image and is represented as the digital object on the background. The digital object only to some extent can approximate the object given in the continuous Euclidean space. The archetype, which is a member of the shape classes, is seen as an ideal geometrical object that is represented by its symbolic name. In this chapter the description of the reasoning process that leads to assigning the perceived object into one of the shape classes is presented.
