Chang S.-K., Jungert E. Symbolic Projection for Image Information Retrieval and Spatial Reasoning
Издательство Academic Press, 1996, -339 pp.
This book addresses image information retrieval and spatial reasoning, focusing on an approach called Symbolic Projection, which supports descriptions of the image content on the basis of the spatial relationships between the objects in the image. Symbolic Projection forms the basis of a growing number of image information retrieval algorithms, and also supports query by picture. As often is the case in the advancement of science, the original idea first came as an intuition to one of the authors. In early 1984, while working on image information retrieval, Chang recalled his earlier research on the reconstruction of binary and gray-level images from projections, and thought it would be nice if symbolic images can be treated in the same way. In other words, if the symbolic image can be projected onto the two orthogonal axes so that the spatial relationships among the objects in the symbolic can be preserved in the projections, then the symbolic image perhaps can also be reconstructed from such projections. This intuitive idea led to the 2D strings for iconic indexing, and later the theory of Symbolic Projection.
The book represents many years of work on the part of both of the authors and is also a testimony of our friendship. When we first started our collaboration the Internet was in its infancy and long-distance cooperation across two continents was still relatively uncommon. We somehow have managed to work together for nearly fifteen years. The book documents the contributions by research groups from all over the world on the theory of Symbolic Projection, as well as our work on spatial reasoning which was among the first in developing this new research area. Also we decided to include many examples, practical applications and system design considerations so that it will serve as a useful overview for designers, practitioners and researchers of image information systems and multimedia systems. Image information systems have a wide variety of applications, including robotics, medical pictorial archiving, computer-aided design, and geographical informations systems, and this book is comprehensively illustrated with examples from these areas. It can also be used as a reference or textbook in a graduate seminar on advanced information systems, image information systems or multimedia information systems.
