Beam Search Algorithm for Fingerprint Reference Point Determination Based on Joint Orientation Features

Shan Juan Xie | Yanshuang Zhang

Abstract: In this paper, we propose an efficient beam search algorithm for fingerprint reference point determination with its joint orientation features, which operates in two-step as well as two-path. For the two-path operation, it uses different orientation features at different scales block-based orientation certainty and pixel-based orientation map. While some fault symptoms are roughly pruned by a block-based orientation feature which is used to ignore some local maxima and select some candidate regions for a reference point region and an accurate path to a reference point is guided by a pixel-based orientation map, their information also is fused for making up one anothers weakness. For the two-step operation, in the first step, several candidates of a reference point are determined through beam search algorithm and, in the second step, an accurate reference point is located through the specic concept models. The proposed system has pixel-based precision in determining the position of reference point without complex enhancement, which has been successfully tested through the database FVC2004.
