Abstract :
Mathematical Morphology provides an alternative to classical filtering methods, such as convolution. To replace linearity by the increasing condition leads to the class of the M-filters. Although they are not invertible, they remove very accurately specific features from the images (peaks but not holes for ex.). The particular case of the opening is discussed and illustrated by an example drawn from astronomy.
