| Abstract: | In this paper, a simpler image pre-processing algorithm for segmentation of fingerprint image is proposed, which can improve the accuracy and reliability of the automatic recognition of fingerprint images. This paper proposes an algorithm, which by reasonable using the gray-level-statistics of fingerprint images, resolves the problem of fingerprint image segmentation with low computational cost. The algorithm has good process result and runs faster and easily to be programmed. The experimental result shows that this segmentation algorithm is more effective and robust the pre-process of the fingerprint images. |
