KNOWLEDGE IDENTIFICATION RENEWAL: FROM WORKINGS TO IMAGE

M.Vidya Rani, Dr R China Appala Naidu

Abstract


While several fingerprint renovation techniques were recommended within the last works, matching performance of reconstructed fingerprints during comparison for the original fingerprint images remains not so acceptable. The reconstructed fingerprint image is less such as the original pistol safe image that minutiae were removed. The responsible for this insufficient matching performance is not any previous knowledge of fingerprint ridge arrangement was applied of people renovation approach to breed fingerprint features. Inside our work we submit an equation of renovation which utilizes previous knowledge of fingerprint ridge structure to acquire better reconstructed fingerprint image. Previous more understanding about fingerprint ridge structures is encoded as orientation patch additionally to continuous phase patch dictionaries to acquire better fingerprint renovation. The orientation patch dictionary is required to rebuild orientation field from minutiae, because the constant phase patch dictionary is needed to rebuild ridge pattern.
