%X Fingerprint image quality estimation is an important step of Automatic Fingerprint Identify System (AFIS). The quality of fingerprint image from fingerprint machine seriously affects preprocess and identification. The exiting detailed regulations were analyzed, the influence on fingerprint quality from valid area, range of gray level, dry, wet to deflect were discussed. A new method was proposed to estimate fingerprint image quality based on information about edge-minutiaes, and qualified fingerprint images were provided. Experimental results show that it can filter unqualified fingerprint image effectively, and it is helpful to raise the efficiency of whole system.
