In this paper, a novel method for retina verification based on minutiae features is proposed. The method uses the vessel direction information for improved matching robustness, and is thus suitable for cases where the overlapping region of the matched images is limited. Verification achieves a low false rejection ratio (FRR) even when the retinal area(More)
