Image Segmentation Using Parametric Contours With Free Endpoints

Benninghoff, Heike ; Garcke, Harald



Abstract

In this paper, we introduce a novel approach for active contours with free endpoints. A scheme for image segmentation is presented based on a discrete version of the Mumford-Shah functional where the contours can be both closed and open curves. Additional to a flow of the curves in normal direction, evolution laws for the tangential flow of the endpoints are derived. Using a parametric approach ...
