%X To extract finger vein features effectively and efficiently, a novel algorithm based on oriented filter for finger vein extraction is proposed. According to the characteristics of finger vein, the proposed algorithm generates a directional image of the finger vein image and a group of oriented filters, with which to filter the image depending on the orientation of the local ridge. Finally, finger vein feature is extracted from the enhanced image. Our method extends traditional image segmentation methods, by extracting vein object from the oriented filter enhanced image. Experimental results show that, apart from smoothness and continuity or removal of noise and pseudo-vein characteristics, the method proposed in this paper extracts vein features effectively not only from the high-quality images but also from the low-quality vein images.
