Abstract
This paper presents a new deformable model based on charged particle dynamics and geometric contour propagation. It detects object boundaries with a charged active contour that propagates under the influence of Lorentz forces in an image-based electrostatic field. We make use of level set representation to allow topological changes to be handled naturally. Also, we build on the centre of divergence concept towards automatic initialisation
