Existence and uniqueness results for the Gradient Vector Flow and geodesic active contours mixed model
Laurence Guillot 1, Maïtine Bergounioux 1
(09/02/2007)

This article deals with the so called GVF (Gradient Vector Flow) introduced by C. Xu, J.L. Prince . We give existence and uniqueness results for the front propagation flow for boundary extraction that was initiated by Paragios, Mellina-Gottardo et Ralmesh . The model combines the geodesic active contour flow and the GVF to determine the geometric flow. The motion equation is considered within a level set formulation to result an Hamilton-Jacobi equation.
