基于多元EMD方法的遥感图像融合

Remote sensing image fusion based on multivariate empirical mode decompostion

在原有的EMD算法基础上,利用多元EMD算法对遥感图像进行融合,该算法将图像看做多元变量,并将其投影到相应的方向向量上,从而获得相应的固有模式函数及残余分量。通过遥感全色图像与多光谱图像的融合证明该算法在既保持了光谱信息的同时,又增强了其空间细节。

A fusion scheme for multispectral image and panchromatic image is proposed based on original EMD（empirical mode decomposition）algorithm.To use multivariate EMD,firstly it look the image as multivariate,and project them into corresponding directional vectors,therefore it gets intrinsic mode functions and residual.At last,experiment is made and results show that this algorithm is not only preserve spectral information but also get a image containing more space details.
