摘 要: 提出一种适合图像融合的非抽样形态小波的构造方法.采用新的非线性滤波器组描述形态小波,去掉其中下采样部分实现非抽样,并将其用于图像融合,用以克服形态小波方法的块状效应.构造适用于所有类型图像融合的S-变换形态小波,通过增加通道和引入增强效果,提高图像融合效果. A method of constructing undecimated morphological wavelets (UMW) applicable to image fusion is proposed in this paper. Firstly, the traditional morphological waveletes (MW) are represented with a novel non-linear filter banks. Secondly, the UMW is constructed by removing the downsampling to overcome the block effect of the MW based image fusion methods. Thirdly, a non-separable S-transform MW applicable to all kinds of image fusion is presented. By expanding UMW to multiplechannels and adding an enhancement factor, the quality of image fusion is improved.
