摘要
Recent progress in fingerprint reconstruction has shown that most of the fingerprint information can be restored using only the minutia set. During the reconstruction procedures, orientation field reconstruction is a critical step. Proposed is a Gaussian weighted method for fingerprint orientation field reconstruction from the minutia template only. In the method, prior information about ridge flow characteristics is considered to more accurately model the ridge orientation. Experimental results show that our method can obtain an accurate orientation field in terms of the accuracy of the orientation field based fingerprint classification and the performance of the orientation descriptor based fingerprint matching.
