Palm-print recognition based on quality estimation and feature dimension

Abstract

Human identification exploitation biometric traits are more and more in style in recent years. Among the widely used biometric traits, palm-print is a vital one because of its acquisition convenience and comparatively high recognition results. The paper proposes a palm-print recognition system based on quality estimation and feature dimensions. Initially, a quality assessment is applied on the extracted region of interest (ROI) images. Gabor filter is employed to extract the palm-print features having various scales and orientations. The kernel-based dimensionality reduction is applied in the full space that reduces the high-dimensional Gabor features. The experiments are conducted on the PolyU, IIT-Delhi and CASIA palm-print databases. The best recognition performance in terms of an equal error rate (EER) of 0.051% and recognition rate (RR) of 98.34% was achieved on PolyU database. Experimental results prove the effectiveness of the proposed approach.
