An algorithm of remote sensing image fusion based on nonsubsampled contourlet transform

Abstract

This paper presents a remote sensing image fusion method based on multiresolution analysis (MRA). The lower spatial resolution multispectral (MS) images are sharpened by injecting high frequency components which are extracted from higher spatial resolution panchromatic (Pan) images by using nonsubsampled contourlet transform (NSCT). In order to improve the… (More)
