Computer graphics and machine image processing represent the generative and receptive aspects of computer-assisted handling of visual information. They play a significant role in design, construction, quality control, and process management in industry, as well as in visualization and signal analysis in medicine and experimental science. Their importance is growing in transportation, media, and for art and culture. By focusing on the application of their specific methods and mutual acceptance of standards, new applications and effective solutions are to be expected. The necessary stimulation is provided by the lexicon, which offers explanations that are also understandable to non-specialists. Fundamental relationships and methods are further clarified through formulas. Various German terms are defined and referenced.
