Since the first edition of Digital Image Processing was published in 1986 it has found its way to many desks and classrooms. The book offers an integral view of image processing from image acquisition to the extraction of the data of interest. The discussion of the general concepts is supplemented with examples from applications on PC-based image processing systems and ready-to-use implementations of important algorithms. The sixth edition has been revised and extended. The complete text of the book is available on the accompanying CD-ROM. It is hyperlinked so that it can be used in a very flexible way. The CD-ROM contains a full set of exercises to all topics covered by this book and a runtime version of the image processing software heurisko. All algorithms discussed can be processed by the accompanying computer programs. A large collection of images, image sequences, and volumetric images is available for practical exercises.
