heal.abstract	In this paper, we propose a novel mathematical model to address segmentation from an aerial and satellite imagery. Segmentation is performed through the consistent recovery of the zero iso-surfaces of a level set function towards image's foreground (desired object for extraction) and background discrimination. The level set method is embedded in a geodesic active contours variational formulation. Geodesic active contours	en
