Symbolic Representation and Reasoning for Rectangles with Superposition

摘要

This paper discusses the superposition of qualitative rectangles so that some parts are visible and other parts are hidden based on the user's requirements. Qualitative rectangles are rectangles whose size and edge ratios are not fixed. We investigate the conditions under which such a superposition succeeds as well as the manner in which such superposition occurs. We also show an algorithm for superposing a multiple number of qualitative rectangles. It is applicable to construct qualitative spatial database for multiple window placement systems.
