Extraction des zones cohérentes par l'analyse spatio-temporelle d'images de télédétection

Abstract : This paper presents a segmentation method of satellite images time series (SITS) in coherent areas, i.e. in geographical regions having homogeneous temporal behavior. The aim of the method is firstly to extract space-time characteristics of an observed region and secondly to obtain this characterization efficiently in terms of computing cost. This method is applied to the characterization of agro-ecological regions of Senegal by the analysis of MODIS images on one year (23 dates).
