摘要 提出一种新的指纹图像增强算法,该算法以小波变换为基础,利用小波的多尺度分析的能力,根据尺度不同进行非线性增强,解决了因噪声过强而造成差的指纹图像质量,同时保证了图像的整体增强效果。 Propose a new kind of fingerprint image enhancement method based on wavelet transform, Make a good use of the multi-scale analysis capability of wavelet, carry on the different enhancement with the change of multi-scale. Resolving the problem of fingerprint image quality because of the heavy noise and make sure the entirety enhancement effect of fingerprint image.
