| Abstract: | The ridgelines tracing technology based on neighbor-coding and its tracing process are introduced. On the base of it, the fingerprint image post-processing algorithms are improved and the fingerprint minutiae are extracted. By eliminating the possible false minutia and extracting the genuine minutiae on entirely-thinned fingerprint image, the effect of post-processing is perfect. The aim can be achieved that fingerprint minutia correctly extracting and minutia collection exactly founding. It can provide an ideal prepare for next work-fingerprint matching. |
