Object hypothesis support in the context of knowledge-based fuzzy-possibilistic fusion of image descriptions

Single images are often not enough to reveal all of the information contained in them, either because of the measurement ambiguity or because of the observer´s imperfect knowledge. Integrating or fusing many knowledge sources is a recent trend in the pattern recognition field. In the work presented in this paper, fuzzy logic, which has been established to be a successful methodology in dealing with imprecision, provides a general conceptual framework and an analytical tool as well.
