The method consists of tree steps: enhancement, contour segmentation, and feature selection. In this study, our method is able to enhance the signals from masses and extract the useful contour feature from the segmented regions. The ruler method of fractal dimension computed for each case was used to form a contour feature. These feature measures can be input to a classifier based on sorting. The experimental results show that our scheme can provide useful contour extraction for spiculation structures in mammographic images.
