Abstract: We present a fingerprint image segmentation algorithm based on support vector machines(SVM). The algorithm uses the features of the gray variance and contrast to train the SVM for image segmentation, and fits the segmentation result of the SVM to convex hull. The experimental results show the algorithm is robust, especially for training segmentation algorithm with a small quantity of samples.
