摘要 图像融合是指联合两个或两个以上的图像通过某种算法得到一幅更高质量的新图像。提出了一种融合全色图像和光谱图像的方法即能量最小化方法,能量主要由两个部分组成。第1部分保证了相关细节信息的注入。第2部分保持了多光谱图像的低频信息。另外,能量还可以包含高分辨率光谱图像的先验知识和其它一些约束条件。 Image fusion is the combination of two or more images to obtain a new image of better quality using a certain algorithm. An energy minimization method which can fuse panchromatic image and multispectral image is proposed. The energy mainly consists of two components. One ensures the injection of more correlated detail spatial information. The other ensures the preservation of the spectral information. Additionally, prior knowledge about the high spatial resolution multispectral image and other constraints can also add to the energy.
