【摘要】 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。更多还原

【Abstract】 Multiwavelet is a new kind of wavelet,it is attached importance to its superiority on theory and its potential on applica- tions.Multiwavelets have found many new applications to signal processing these years.Lifting scheme is not only a fast algorithm of ex- isting wavelet transforms,but also a tool to produce new wavelet transforms.According to the characteristic of the lifting scheme and mul- tiwavelet transform,we present a new lifting scheme for multiwavelet transforms in this paper,and applied this new lifting scheme to im- age fusion.We have achieved better results.更多还原
