| Abstract: | A new contactless device was designed to collect high resolution palmprint images.A novel multiple-scale feature extraction algorithm with a high resolution was proposed based on ridgelet transform.A coarse-to-fine hierarchical matching apporach was presented to improve the speed of feature matching on dealing with high rosolution images.Theoretical and experimental results demonstrate the effectiveness of the proposed algorithm. |
