Methods, systems and computer program products for fusion of high spatial resolution imagery with lower spatial resolution imagery using correspondence analysis

摘要

Methods, systems and computer program products are provided for fusing images having different spatial resolutions, for example, different spatial and/or spectral resolutions. Data for at least two images having different spatial resolutions is obtained. A component analysis transform is performed on a lower spatial resolution image of the at least two images. A component of the component analysis transform of the lower resolution image containing a small amount of information associated with the low spatial resolution image is replaced with information from a higher spatial resolution image of the at least two images.
