This paper presents an extension of our recently introduced MAC model to deal with the initialization dependency problem that commonly appears in edge-based approaches. Its dynamic force field, unique bidirectionality, and constrained diffusion-based level set evolution provide great freedom in contour initialization and show significant improvements in initialization independency compared to other edge-based techniques. It can handle more sophisticated topological changes than splitting and

It provides new potentials for edge-based active contour methods, particularly when detecting and localizing objects with unknown location, geometry, and topology. Index Terms-Active contour, edge based, initialization flexibility, level set method, object segmentation.
