An Algorithm for Fingerprint Incomplete Regions Reconstruction from Minutiae and Orientation Field
摘要
Abstract
An incomplete fingerprint is one which contains noise and cannot be recognized in some areas.In some cases, it may not provide sufficient minutiae or ridge details for undertaking a normal matching process.This paper proposes an algorithm to reconstruct incomplete regions. The nearest minutiae and orientation field of neighborhood are combined to estimate the unknown orientation field. Previous outcome is used to connect disrupted ridges and recover missed minutiae based on ridge topology features, and arrive several rational schemes. They are measured by using entropy and the best is chosen. The experimental results demonstrate that proposed algorithm is effective in reconstructing incomplete fingerprint, and hence improve the performance of matching.关键词
