摘要
介绍了小波理论在图像处理领域的应用现状,详细介绍了小波阈值去噪算法,并利用小波阈值算法对差的指纹图像进行了处理,解决了因噪声过强而造成的差的指纹图像质量,同时保证了图像的整体增强效果。
In order to introduce the present situation of image process in wavelet transform and the threshold algorithm method based on wavelet transform,make use of this method to process the finger print image,Resolving the problem of finger print image quality because of the heavy noise and make sure the entirety enhancement effect of finger print image.
