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.",
