Shape-based Active Contours for Fast Video Segmentation

IEEE Signal Processing Letters Volume 16, Number 10, pp. 857-860, 2009.


In this letter, we propose a shape-based active contours method for segmentation, based on a piecewise-constant approximation of the Mumford–Shah (M–S) functional. The Chan–Vese (C–V) formalism in a level set framework is used to formulate our method; however no sign distance function (SDF) is employed in the method proposed here. This method has the topology-free segmentation associated with the C–V algorithm and adds faster convergence, less memory requirement and fast re-initialization. These properties make the algorithm very attractive for video segmentation.
