This is a reference work from which the reader should be able to understand current digital imaging technology, terms and relationships. From a basic understanding of optics, imaging systems and necessary technology, the reader should be able to follow future developments in the rapidly growing area of imaging. The book provides background information and an introduction to modern imaging science. It should, therefore, find a place in companies ionvolved in imaging, publishing, mapping and remote sensing and related sectors, and should also be relevant for colleges and universities, particularly those that teach physics, information technology, photography, electronics and any subject that uses images as a data source. The final part of the book introduces a number of applications to stimulate interest and illustrate the potential of this rapidly growing technology.
