Comparing active contours for the segmentation of biomedical images
Birgit Möller, Stefan Posch · 2012
Application of active contours for image segmentation raises the question of contour representation, i.e. whether to use snakes or level sets. The representation directly affects issues like topology-preservation and energy optimization. In this paper we aim to contribute to the understanding of specific characteristics of contour representations with a detailed comparison of snakes vs. non-PDE level sets. Based on the same energy functional and applied to different kinds of real-world data our experiments show minor differences in segmentation quality, but outline important distinctions regarding implementation, parameter settings and computational effort.
