| 摘 要： | 多小波分析能够为图像提供一种比小波多分辨率分析更加精确的分析方法.彩色图像的表现形式主要有RGB混色系统和IHS显色系统.为了得到高质量遥感图像的融合效果,将多小波变换分别和2种系统结合,以GHM多小波为例,采用梯度加权算法,通过Matlab编程实验,得出了多小波变换和2种系统结合的各自优缺点,突出了多小波变换和RGB系统相结合的优势,实验结果明显.

| Abstract: | Multiwavelet analysis can offer a more precise way for image analysis than wavelet multi-resolution analysis.The two expressions of color image are mixed color system and shown color system.In order to get a better fusion result of remote sensing images,we unified multiwavelet transform and the two systems,takeing GHM multiwavelet as the example,using gradient addition method,programming by Matlab,and got the advantages and disadvantages of the two systems unified by multiwavelet transform.It highlighted th... |
