Abstract

Based on the global orientation

the local gradient and the mutual information function

a novel fingerprint orientation field fusion algorithm is proposed for incomplete fingerprint orientation field reconstruction.First

according to the properties of competition of the local fingerprint

complementation and redundancy of the global fingerprint

the gradient dispersion function is proposed

adaptively.Then

the fingerprint orientation field of the incomplete area is re-computed and measured by mutual information function.And hence the fusion orientation field is used for Gabor filtering and minutiae matching.The experimental results indicate that the proposed algorithm is effective for incomplete fingerprint.
