The processing of digital images by computers constitutes a new challenge t computer science because a huge amount of data has to be processed in extremely short time. This necessitates the development of new parallel process and operation structures to achieve acceptable response times. The tasks of preprocessing steps include the removal of noise, the calibration of the images and the enhancement of image quality. The resulting images are input to procedures that transform their contents into a compact form suitable within the scope of the given application. The ultimate goal is to make a rich set of methods for image analysis available and to apply them to different areas. A broad-ranging technical survey of computational and analytical methods and tools for digital image analysis and interpretation. An excellent, up-to-date resource for computer scientists\' and engineers\' digital imaginging and analysis.
