A MBR-Based Approach for Modeling Direction Relations between Uncertain Regions
Shengsheng Wang · Dianzi xuebao · 2011
Most regions in real world have uncertain boundaries.The present models based on crisp regions can not deal with the Direction Relations between the Regions with Uncertain Boundaries(DRRUB).Using broad boundary to represent the uncertain boundary,a novel approach based on the model of MBR(minimum bounding rectangle)is proposed for modeling DRRUB.In this paper,DRRUB are described by MBR-based cardinal direction relations and rectangle algebra,then we study the consistency-based composition of DRRUB,and a method is put forward for calculating this consistency-based composition.
