This paper presents a new method for automatic segmentation of thermographic frontal breast images. First, the method uses a low-pass filter and the topological derivative to get a rough definition of the region of interest (ROI). Then, the previous result is used to initialize the method proposed by Marques. This method uses the adjustment of curves by Quadratic Uniform B-Splines. The efficiency of the proposed method is quantitatively verified using a ground truth developed by a group of… CONTINUE READING
