Aiming at the application of palmprint recognition in mobile devices,this paper proposes a palmprint recognition algorithm and successfully embeds it into Lenovo ET980 mobile phone.The mobile-based system captures and pre-processes palmprint image in a new style.An optimal Gabor wavelets based discriminant subspace method is applied for feature extraction to give an effective and compact presentation of palmprim image.The system achieves the recognition rate of EER=3.89% and takes 1s to verify a palmprint image,which satisfies the requirement of a real-time verification system.
