Detecção de arestas com o tensor de estrutura

Abstract

Urich Köthe proposes improvements in the calculation of the structure tensor, that will be presented in this work. First, the tax of sampling is altered, therefore the standard method for calculation of that tensor violates the Shannon s sampling theorem; at second, using a non-linear filter to calculate the entrances of the structure tensor, the integration of information coming from out of the edge is minimized.
