| 摘 要： | 详细介绍了构造第二代小波的上升方案,并实现了Cohen-Daubechies-Feauwell(CDF)(2,2)双正交小波。与传统小波变换相比基于上升方案的小波变换具有构造简单、运算方便的特点,而且可以根据实际需要构造新的小波。在传统小波图像融合算法的基础上,本文提出了更为通用的小波变换融合方法,在基于子带的融合过程中体现了高频信息的竞争以及低频信息的协同,这既考虑了如何克服因为待融合影像不同的成像方式带来的块效应,又能方便的根据用户需要改善影像融合质量。

| Abstract: | The lifting scheme of wavelet was introduced in this thesis and Cohen-Daubechies-Feauwell(CDF)(2,2)Biorthogonal Wavelet constructed by lifting scheme was made use in image fusion.It can be proved that wavelet transform constructed by lifting scheme has advantages such as constructed simply and calculated conveniently and it can be made good use in image fusion.In this paper,a improved image fusion method based on traditional ones was introduced.To all appearances this method indicated the full use of high and low image frequencies,but also,it indicated the mechanism of correct use of different remote sensing sensors. |
