In this paper we address a key issue in scenario classification, where classifying concepts show a natural overlapping. In fact, overlapping needs to be evaluated whenever classes are not crisp, in order to be able to check if a certain classification structure fits reality and still can be useful for our declared
decision making
purposes. In this paper we address an
object recognition
problem, where the best classification with respect to background is the one with less overlapping between the class object and the class background. In particular, in this paper we present the basic properties that must be fulfilled by overlap functions, associated to the degree of overlapping between two classes. In order to define these overlap functions we take as reference properties like migrativity, homogeneity of order 1 and homogeneity of order 2. Hence we define overlap functions, proposing a construction method and analyzing the conditions ensuring that tnorms are overlap functions. In addition, we present a characterization of migrative and strict overlap functions by means of automorphisms.

...It would be the case, for example, when we consider the aggregation of several measures obtained by different experts: a well known problem in remote sensing is to chose an adequate distance in order to compare opinions from different experts (the analysis of ignorance and overlap measures will be extremely pertinent here, see [2], [
