摘 要
给出了一种基于离散正交小波变换的图象去噪方法,该方法通过二维离散小波变换将图象投影到小波变换域,通过对小波变换系数进行阈值处理实现二维图象的去噪,并用实验验证了该方法的有效性。

Abstract
This paper studies an images moother based on two dimensional discrete orthogonal wavelet transform. By thresholding the wavelet transform coefficients of noisy images, the original image can be reconstracted correctly. Simulations show this denoising method is valid.
