| Abstract | The Dual-T-Snakes model plus dynamic programming (DP) techniques is an efficient methodology for boundary extraction and segmentation of 2D images. However, the original proposal of the Dual-T-Snakes suffers from difficulties for parameters choise and instabilities due to the normal force definition. Also, the proposed method to push a snake way from a local minimum is not efficient for noise images. In this paper we address these limitations. Firstly, we reduce the number of parameters without affecting the basic features of Dual-T-Snakes. Next, we propose a new normal force definition which maintains the desired features of a balloon-like one but is more stable and gives better performance. Then, we propose other methods to avoid local minima based on mesh resolution, image statistics and a new region growing technique. We demonstrate these methods for artificial and cell images. Finally, in the future works, we figure out how to apply Dual-T-Snakes plus Viterbi together with non-parametric multiscale methods. |
