Abstract: Multiwavelet transform can meet the merits at the same time，such as regular and orthogonal，compact support，but scalar wavelet can not.Therefore，it attracts a lot of concern in the field of image processing.Based on the dependencies between
neighboring coefficients，a new weighted multiwavelet matrix thresholding rule is proposed.And the experiment proves
that it is an effective way to remove noise.

摘要： 多小波变换同时拥有正则性、正交性、紧支性、对称性等单小波不能同时满足的优点，近年来在图像处理领域受到了广泛关注。利用多小波变换后系数之间存在的大量的相关性的特点，提出了一种新的小波阈值方法。通过仿真实验，证明了该方法能有效地去除噪声。
