Abstract
In order to guarantee consistent descriptions of image structure, it is
desirable to base such descriptions on topological principles. Thus, we
want to be able to derive topological representations from segmented
images. This paper discusses two methods to achieve this goal by means of
the recently introduced XPMaps. First, it improves an existing algorithm
that derives topological representations from region images and crack
edges, and second, it presents a new algorithm that can be applied to
standard 8-connected edge images.
