                         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.",
