A picture cannot convey with dueprecision the mathematical underpinnings of the discoveries of Galileo or Pas-cal nor can a picture give expression to the philosophy of Augustine, Plato, orEdwards. Nonetheless, while pictures do not carry the precision of written language they do contain a wealth of information and have been used throughoutthe centuries as an important and useful means of communication. an image isa picture representing visual information. a digital image is an image that can bestored in digital formPrior to the advent of computation, images were rendered on papyrus, paper,film, or canvas using ink or paint or photosensitive chemicals. These non-digitalimages are prone to fading and hence suffer loss of image quality due to exposureto light or temperature extremes. Also, since non-digital images are fixed insome physical medium it is not possible to precisely copy a non-digital imageThroughout the annals of art history, forgers have attempted to copy paintings ofwell-known masters but usually fail due to their inability to precisely duplicateeither a style or an original work. Han van Meegeren is one of the best knownart forgers of the 20th century. His technique so closely mimicked the style andcolors of the art masters that he was able to deceive even the most expert artcritics of his time. His most famous forgery, The Disciples at Emmaus, was createdin 1936 and was purportedly created by the well-known Dutch artist JohannesVermeer. His work was finally exposed as fraudulent, however, at least in partby a chemical analysis of the paint, which showed traces of a plastic compoundthatnot manufactured until the 20th century!Digital images, however, are pictures that are stored in digital form and thatare viewable on some computing system. Since digital images are stored as bi-nary data, the digital image never fades or degrades over time and the only way
