摘要: 在图像的小波阈值去噪中,为了提高阈值的准确度,引入了迭代算法。实验结果表明,与普通的小波阈值去噪方法相比,该方法不但可以大量保留图像的边缘信息,而且减小降噪图像与原图像的误差。

Abstract: The iterative algorithm is introduced into the analysis of the image denoising via wavelet threshold for the improvement of the threshold’s accuracy.The result of running the program indicates that,compared with the normal image denoising method by wavelet threshold,this method can reserve lots of the image’s fringe information and reduce the error between the result and the original image.
