Computer-aided automatic processing of images requires the identification, encoding or description, and control of a series of operations, a process which this book analyzes. Ascertaining the statistical properties of images, sampling them to reduce the observable world to a series of discrete values, and restoring images in order to correct degradations are among the operations explained here, together with the mathematical tools they require. Topics covered include fractal representation, mathematical morphology, wavelet representations and the detection and description of contours and shapes.Â
