Multiresolution shape representation without bordershifting
Luciano da Fontoura Costa, Leandro F. Estrozi · Electronics Letters · 1999
The authors show how exact dilations can be used to obtain multiresolution skeletons and how a new multiresolution approach to shape representation can be achieved in terms of such skeletons. In addition to allowing the accurate reconstruction of multiresolution versions of the original binary shapes, the proposed approach is characterised by great simplicity and the important property that the shape borders are not shifted as the smoothing increases.
