Michael Jüttner,Sébastien Ferreira-CercaWhen objects are detected with suitable operators and their shape is described (see chapter 11), image processing has reached its goal for some applications. For other applications, further tasks remain to be solved. In this introduction we explore several examples which illustrate how the image processing tasks depend on the questions we pose.

Image Formation and Digitization,ages requires a good understanding of the image formation process. Only with a profound knowledge of all the steps involved in image acquisition, is it possible to interpret the contents of an image correctly.

Proceeding now to discrete imagery, the question arises whether there is a discrete analogue to the continuous Fourier transform. Such a transformation would allow us to decompose a discre

This approach enables us to regard image formation as a measuring process which is corrupted by noise and systematic errors. Thus we learn to handle image data as statistical quantities.
