WebGeodesic Active Contours 63 Riemannian space derived from the image. From this geodesic model for object detection, we derive a novel geometric partial differential equation for active con-tours that improves previous curve evolution models. 2.1. Energy Based Active Contours Let us briefly describe the classical energy based snakes. WebOVERVIEW. This class is a level set method segmentation filter. An initial contour is propagated outwards (or inwards) until it ‘’sticks’’ to the shape boundaries. This is done by using a level set speed function based on a user supplied edge potential map.
