摘要
多小波是一种新的小波 ,他在理论上所表现出来的优势以及他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 ,他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。根据提升方法和多小波变换的特点 ,介绍了一种实现多小波变换的提升方法 ,并把这种提升多小波变换应用于图像处理 ,结果表明有很好的效果。
Multiwavelet is a new kind of wavelet, it is attached importance to its superiority on theory and its potential on applications. Multiwavelet has found many new applications to image processing these year. 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 introduced a lifting scheme for multiwavelet transforms in this paper, then, we used the lifting multiwavelet transform in image processing. We have achieved better effective results.
