A novel finger vein pattern extraction method using oriented filtering technology

To extract finger vein features effectively and efficiently, a novel algorithm based on oriented filter for finger vein extraction is proposed. The proposed algorithm calculates a direction map and uses a group of designed oriented filters to facilitate the extraction of the characteristic vein pattern from the enhanced finger vein image. Experimental results show that this new algorithm not only extracts smooth and continuous vein features, but also effective in removing noise from low-quality images.
