                         image analysis. This work presents a comparative study between two 
                         active contour approaches for image segmentation. Level sets 
                         method and deformable contours under B-spline representation are 
                         compared. These image segmentation methods have different features 
                         and are difficult to compare in terms of performance, accuracy and 
                         initialization conditions. Both are implemented and a way to 
                         calculate the approximation error is developed. As a conclusion of 
                         this work a theoretical comparison and a comparative 
                         characterization of the approximation error for each method are 
                         presented.",
