Here we show that a notion of congruence in statistical structure across 2 0 frequency bands produces a useful definition of visual patterns for perceiving target distinctness. In order to reach such a conclusion, ,firstly, the notion of congruence is used to induce a representational model for 2 0 images. Secondly, the visual-pattern based(More)
In this paper a watershed-based algorithm to segment biomedical digital images into a number of diierent signiicant regions is presented. The proposed algorithm is based on a generalization of the geodesic innuence zone concept. This generalization and the estimation of the involved parameters are described. Once the regions are obtained, we have the(More)
