摘要	Minutiae extraction for automatic fingerprint identification system is one of the most important steps. However, the performance of minutiae extraction relies heavily on an enhancement algorithm. There are many algorithms of enhancement that depend on the local orientation field of fingerprint. In the singular point area, because the local orientation changes very rapidly, we almost cannot make it accurate. So, the result of enhancement in the singular point is very bad. In this letter, we present a new method and design a new filter to enhance fingerprint in the singular point area. We distinguish the singular point area first. Then we design a new filter to enhancement this area. Finally, we give results and conclusion. Experimental results show a significant improvement of the fingerprint enhancement in the singular point area, and the time is required for our algorithm is reduced.
