Describing and Abstracting Pictorial Structures,
Abstract
As part of the research into the nature of descriptive representations of photographic material, it was necessary to obtain answers to questions concerned with the state-of-the-art in indexing and describing pictorial data, and factors that must be considered in designing systems or experiments involving scene and picture description. In addition to a discussion of the descriptive process in general, three main classes of formal description are considered: the grammar-based approach, which uses a set of rules to describe the arrangement and relationships among the picture primitives; the descriptor-based approach, which captures the content of the picture by using a number of terms or phrases; and the procedure-based approach, in which a system (possibly grammar based) capable of generating a large number of descriptions is coupled to a high level control mechanism which selects procedures and order of procedures so as to produce only a single desired description.
