Image segmentation is a basic and important problem in the field of computer vision. A recent geometric approach for image segmentation is the geodesic active contour based on the level-set method. One drawback of the method, is the extended numerical support that makes its solution time consuming. We propose to solve an implicit system of the geodesic active contour model using the computationally efficient multigrid method.
