Détermination d’une ligne de rivage de grande taille à l’aide de la multi résolution hiérarchique sur une image RSO
The goal of this study is to evaluate the coastline length on a series of images reduced by the hierarchical multiresolution technique and extracted from a synthetic aperture radar image (SAR) of theERS-1 satellite, of very great size. In this study, the edge detection technique and the mathematical...
