摘要
介绍了小波变换技术,并采用小波分解与重构方法对指纹图像进行小波压缩、去噪和增强处理.实验表明,应用小波变换技术对指纹图像进行处理能够获得较满意的结果.
The fingerprint is regarded as a kind of biological characteristic of human beings. It has the advantages of uniqueness stability, being able to gather, never being able to be from the subject, etc. It has already become the effective means that the personal identity has discerned. In this paper, the wavelet transform is introduced, and then based on wavelet decomposition and reconstruction, the fingerprint image compressing,getting rid of noise and extracting features are fulfilled. Experimental results have verified that this method is effective in preprocessing fingerprint images.
