Paper Abstract

The processing of images on a digital computer is usually done for the purpose of extracting information from an image which the unaided human visual system cannot extract by itself. In nearly all image processing procedures a large amount of a priori knowledge related to the image must be utilized in order to extract the desired information. By a priori knowledge we mean knowledge about the image obtained from sources other than the image itself. This knowledge might include information about the object, the transmission media, the optical system, the sensor, the scanning and digitizing equipment, and the processing technique. Often a part of the a priori knowledge is contained in the mind of the observer as a result of accumulated experience.
