Digital Images

Abstract

Digital images are the focus of many computer graphics processes. They are links between the user and these processes, revealing the results of the latter. We may even say that all areas of computer graphics involve digital images, whether as a final product, as in the case of visualization, or as an essential intermediate step in the interaction process, as in the case of modeling. Thus, an understanding of the meaning of images in this context is essential. A rigorous formulation of the various notions associated with digital images is necessary in order to allow an analysis of the data structures used in image representation and of the algorithms used in image creation and manipulation.
