Appendix: Digital topology — A brief introduction and bibliography

Publisher Summary In image processing and computer graphics, an object in the plane or 3-space is approximated digitally by a set of pixels or voxels. Digital topology studies the properties of this set of pixels or voxels that correspond to topological properties of the original object. It provides theoretical foundations for important operations such as digitization, connected component labeling and counting, boundary extraction, contour filling, and thinning. Some basic terminology and fundamental concepts of digital topology are discussed and important areas of the field are described in the chapter.
