A SPATIAL LOGIC FOR SYMBOLIC DESCRIPTION OF IMAGE CONTENTS

Retrieval by contents is a major feature within databases of images, as it permits natural access to information. In order to support effectively this kind of operation, images must be associated with an appropriate description of their contents so as to provide some indexing support during the retrieval stage. To this end, appropriate languages for the representation of spatial information are required. In this paper, an original language, referred to as Spatial Logic, for the representation of spatial relationships between imaged objects is presented. A system which exploits this language to support image retrieval by contents through iconic visual interaction is also presented.
