摘要
将维纳滤波的原理应用到基于平稳小波的X射线图像去噪过程,研究了一种基于平稳小波的X射线图像维纳滤波去噪方法。实验证明:该方法不仅能有效消除Gibbs现象,而且能够在有效滤除噪声的同时,很好地保持X射线图像的细节部分信息。
This paper applies the principle of Wiener filtering to the process of X ray digital image de-noising based on stationary wavelet, provides a method of X ray digital image de-noising based on stationary wavelet in Wiener filtering. Experiment shows that the method not only can eliminate the Gibbs phenomenon, but also can retain detail information of X ray digital image.
