Abstract: A novel contactless collection method was designed for palmprint recognition with high resolution. An image restoration approach based on regularization method and directional wavelet was proposed to solve the problem of the possible resulting defocus images. Theoretical and experimental results demonstrate the effectiveness of the algorithm for imporving the current palmprint collection technique and enhancing the resolution.

Key words: palmprint recoginition, regularitation method, image restoration, ridgelet transform
