Abstract :
Contour-coded binary images on a discrete square grid can be expanded by means of a simple numerical manipulation of their chain code if they are first decomposed into elementary convex patterns. This approach avoids several shape-interpretation problems, arising with arbitrary blobs, and reduces geometrical distortions to a minimum.
