Abstract
This paper presents how morphological transformations can be related t o representations of a set on different lattices. A hierarchical defin ition of structuring element conveys to a class of multigrid transform ations Psi(k) that handle changes on discrete representations of regio ns. The transformations correspond to upward and downward processes in a hierarchical structure. Based on multigrid transformations, requiri ng O(log n) time is presented. The approach considers grey level regio ns as sets and processes through a pyramid to carry out geometric mani pulations. Extending the concept of boundary to cope with hierarchical representations of a set, a second method which identifies the bounda ries in an image is discussed.
