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.

Key words: palmprint recoginition, ridgelet transform, image restoration, hierarchical matching
