                         automatic systems of visual perception, a set of phases that 
                         characterize the computational modelling of the perceptive process 
                         are distinguished. During the segmentation and interpretation 
                         phases, besides the compromise regarding the elimination of 
                         inconsistencies, there appears the ambiguity problem. In this work 
                         it is proposed an approach to deal with those questions, in the 
                         level of the identification of the object, using the semantic 
                         relationships and iterated parallel operations (relaxation 
                         operations) upon a discrete model that labels segments (labelled 
                         graphs). It is intended to reduce to the maximum the ambiguity 
                         through a s-ingle process of successive elimination, instead of a 
                         process for each possible segmentation. The dissertation is based 
                         mainly in the algebraic characterization of the relaxation 
                         operator and in the formal treatment, through discrete algebra, 
                         which puts into evidence its computational validity.",
