Abstract

This paper presents a novel approach of palmprint authentication based on the fusion of the phase and orientation information. This approach is an improvement of a previous palmprint recognition method - FusionCode method [1]. In the proposed approach, the phase information (Fusion-Code) of a palmprint is extracted by using four 2-D Gabor filters with different orientations, and at the same time, the orientation information (called OrientationCode) of the palmprint is also extracted. The FusionCode and the OrientationCode are fused to make a new feature, called the Palmprint Phase Orientation Code (PPOC). At the matching stage, a modified Hamming distance is defined to measure the similarity of two PPOCs. This approach is tested on a palmprint database containing 7605 samples and the experimental results show that the PPOC approach greatly improves the performance of the FusionCode method.
