Abstract
This paper studies the fusion of contextual information in pattern recognition, with applications to biomedical image identifi-
cation. In the real world there are cases where the identity of an object is ambiguous if the classification is based only on its own
features. It is helpful to reduce the ambiguity by utilizing extra information, referred to as context, provided by accompanying
objects. We investigate two techniques that incorporate context. The first approach, based on compound Bayesian theory, incor-
