Palm-dorsal vein recognition based on uniform discrete curvelet transformation

Abstract

Palm-dorsal vein recognition using Uniform Discrete Curvelet Transform(UDCT) was proposed in this paper.With the palm-dorsal Region Of Interest(ROI) extraction and image preprocessing,UDCT of the curvelet Transform was used on ROI.Then,the curvelet coefficients phase variance was encoded.Finally,the Chi-square distance of histogram of the coding was used for vein recognition.The experimental results show that this proposed method can identify palm-dorsal vein images with high robustness and high speed even with poor-quality images.
