Aiming at the existing fingerprint algorithm refinement not refined exist completely swallowed, skeleton, lines from lines problems such as center, the paper puts forward the rapid thinning algorithm, through the analysis of target of the direction of the trend lines around, choose to remove or keep connected point around, effectively solve traditional iteration algorithm has refined the problems, and refining the template image square ridge tracking, overcome the gradually to the main lines tracking algorithm are too complicated and not easy to realize. Finally the improved algorithm in FPS200 fingerprint sensor as acquisition device automatic fingerprint identification system for verification. The results show that the algorithm has a good refined effect, get the details of the image further satisfy the requirements of feature extraction.
