A few years ago, the department of computer science of the University of Magdeburg developed a completely new diploma programme called 'computational visualistics', a curriculum dealing with all aspects of computational pictures. So far, only isolated aspects had been studied in computer science, particularly in the independent domains of computer graphics, image processing, information visualization, and computer vision. Is there indeed a coherent domain of research behind such a curriculum? The answer depends on a data structure that acts as a mediator between general visualistics and computer science: the data structure "image".

Jörg R. J. Schirra investigates that data structure, its components, and its application conditions, and elaborates the very foundations of computational visualistics as a unique and homogeneous field of research. Before concentrating on the data structure, the author closely examines the theory of pictures in general and the definition of pictures as perceptoid signs in particular. He includes an act-theoretic consideration of resemblance as the crucial link between image and object, the communicative function of context building as the central concept for comparing pictures and language, and several modes of reflection underlying the relation between image and image user.
