Quantitative Analysis and Abstraction of Topological Relation Between Regions with Broad Boundaries

Topological relations between regions with broad boundaries are very complicated. It is difficult to distinguish these topological relations by qualitative method. This paper analyzes the 46 topological relations between regions with broad boundaries determined by the "egg-yolk" model proposed by Cohn and others and the clustering of these relations and proposes a quantitative method that can describe these topological relations.
