Abstract—Most systems of fingerprint identification and/or authentication need a ridge direction map, commonly called the orientation map. In addition, the estimation of orientation field plays an important role in the fingerprint enhancement. In this paper, A novel fingerprint orientation map estimation based on Wave atoms transform is proposed. This paper aims to open a new gateway by proposing a different approach for analyzing fingerprints and try to unify steps of automatic fingerprint identification system( AFIS): classification, compression, quality measure,
local orientation and identification. Wave atoms is one of the new geometric multiscale-multidirectional transform, which is more appropriate to represent fingerprint structures. In order to evaluate the performance of the algorithm, FVC2004 database has been considered. The results show that this method has a serious potential in fingerprint orientation evaluation.
Index Terms—fingerprint orientation map, wave atoms transform, multi-directional analysis, orientation field.
