Abstract :
Thinning algorithm for fingerprint image based on directional images is studied deeply in this paper, and a high-efficiency improved algorithm come up. The method of labeled data is used in this paper. On the premise of ensuring the quality, the improved algorithm not only can accelerate the rate of thinning, but also extract the characteristic of the fingerprint.
