Abstract

This paper shows how the Discrete Mereotopology notions of adjacency and neighbourhood between regions
can be exploited through Mathematical Morphology to accept or reject changes resulting from traditional
morphological operations such as closing and opening. This leads to a set of six morphological operations
(here referred to generically as minimal opening and minimal closing ) where minimal changes fulfil specific
spatial constraints. We also present an algorithm to compute the RCC5D and RCC8D relation sets across
multiple regions resulting in a performance improvement of over three orders of magnitude over our previously
published algorithm for Discrete Mereotopology.
