| 摘 要： | 针对IHS变换融合方法不能保持好的光谱信息,张量积小波变换融合方法生成的融合结果图像空间分辨率偏低、且易产生方块效应等不足.提出了一种基于三通道不可分对称小波的多光谱图像融合方法.利用矩阵扩充的方法,给出了三通道不可分对称小波滤波器组的构造方法,用所构造的不可分小波滤波器组分别对多光谱图像的亮度分量和全色图像作非下采样...

| Abstract: | In order to solve the problems that the image fusion method based on IHS transform can not preserve good spectral information and the image fusion method based on separable discrete wavelet transform is low in spatial resolution and block effect is exist in the fused image,a new multispectral image fusion method based on IHS transform and three channels nonseparable symmetrical wavelets is proposed.A construction method of the symmetrical filter bank relating to this kind of wavelet is presented.The multi-r... |
