摘要
掌纹图像去噪是基于掌纹的身份鉴别技术的第一步.本文提出了一种新的基于小波变换的掌纹图像去噪算法,并通过实验验证了此算法对掌纹图像去噪的有效性.
Denoising of palmprint image is the first stage of computer-aided identity recognition based on palmprint. A novel palmprint image denoising algorithm based on wavelet transform is proposed in this paper, and validity of the algorithm is verified by experiment.
