一种新的基于提升多小波变换的图像融合方法

A New Image Fusion method Based on Lifting Multiwavelet Transform

多小波是一种新的小波,它在理论上所表现出来的优势以及它在应用领域所具有的潜力,使其受到高度重视。在短短的几年时间内,它在图像处理方面的应用已取得了一定的成效。提升方法不仅是现存小波变换的一种快速算法,而且是构造新的小波变换的一种工具。本文根据提升方法和多小波变换的特点,对多小波实现了提升变换,并把这种基于提升方法的多小波变换应用于图像融合,结果表明有更好的效果。

Muhiwavelet is a new kind of wavelet, it is attached importance to its superiority on theoly and its potential on applications. Multiwavelets have found many new applications to signal processing these years. Lifting scheme is not only a fast algorithm of existing wavelet transforms, but also a tool to produce new wavelet transforms. According to the characteristic of the lifting scheme and multiwavelet transform, we present a new lifting scheme for multiwavelet transforms in this paper, and applied this new lifting scheme to image fusion. We have achieved better results.
