A simple image pre-proeessing algorithm for segmentation of fingerprint image is proposed, which can improve the accuracy and reliability of the automatic recognition of fingerprint images. This algorithm solves the problem of fingerprint image segmentation with low computational cost based on reasonable application of the gray-level-statistics of fingerprint images. It has good process result and runs quickly and can be programmed easily. The experimental result shows that this segmentation algorithm is more effective and robust to the pre-process of the fingerprint images.
