The two pages available in Postscript (from the MR/1 User Manual) present a stunning example of speckle removal from a SAR (ERS-1) image. They are from the thesis of Y. Bobichon, Restauration d'Image en Multirésolution, Observatoire de la Côte d'Azur, 14 November 1997. See also Méthodes multi-échelles appliquées à l'analyse des images radar à ouverture synthétique, Traitement du Signal, 14 (2), pp. 180-193, 1997.
The MR/1 commands used to carry out the despeckling are indicated in the figure captions.
