Abstract: The contrast is low and the venous structure is simple for the hand vein image captured by near infrared camera. In order to extract the features of hand vein structure effectively, the wavelet decomposition sub-band image was analyzed. The low frequency sub-band image is better as hand vein recognition features. A feature extraction method by wavelet decomposition and mean absolute deviation is proposed in this paper. Then 48 dimensional feature vectors were formed. Finally, the Euclidean distance classification was used to do classify experiment. The results have shown that this method is not sensitive to shift, rotation and scaling in small range. The total recognition rate is 99.25 %, while the false acceptance error rate is 0.
