RESUMO

The motivation of this work comes from the observation of some discrete plane limitations, especially those related with the skeleton and contour extraction. The objective is to overcome these limitations. The methodology consists of using domain transformations. The main contribution is the introduction of an expansion for labeled images and the study of its geometric and topologic properties. The work shows yet that other expansions can solve the extraction of gradual influence zones.
