We analyze a variational approach to image segmentation that isbased on a strictly convex non-quadratic cost functional.The smoothness term combines a standard first-ordermeasure for image regions with a total-variation basedmeasure for signal transitions. Accordingly, the costs associatedwith “discontinuities” are givenby the length of level lines and local image contrast.For real images, this provides a reasonable approximation of thevariational model of Mumford and Shah that has been suggested asa generic approach to image segmentation.The global properties of the convex variational model are favorableto applications: Uniqueness of the solution, continuous dependenceof the solution on both data and parameters, consistent and efficientnumerical approximation of the solution with the FEM-method.Various global and local properties of the convex variational modelare analyzed and illustrated with numerical examples. Apart fromthe favorable global properties, the approach is shown to providea sound mathematical model of a useful locally adaptive smoothingprocess. A comparison is carried out with results of a region-growing technique related to the Mumford-Shah model.
