Abstract
When an active contour is applied to a noisy image, the contour is sometimes attracted to a local energy minimum, since the noise gives rise to high rates of change of the image gray levels. In this paper we will describe a novel method of overcoming this problem by using a sparse set of points to represent the active contour C and randomly varying the positions of these points.
