Résumé en anglais

The Numerical Tours of Signal Processing is an online collection of tutorials to learn advanced computational signal and image processing. These tours allow one to follow a step by step Matlab or Scilab implementation of many important processing algorithms. This implementation is commented and the connexions with the relevant mathematical notions are exposed. These algorithms are applied to various signal, image, movie and 3D mesh datasets. These tours are suitable for practitioners in the field, that can use them to learn about state of the art methods. They are also designed to help undergraduate students to understand recent theoretical or numerical advances in signal and image processing.
