Abstract
Method and system for creating a fused image from an image pair. The method includes obtaining (204) image data defining a first image of a panchromatic image type and a second image of a multi-spectral image type. The first image has a first spatial resolution and a first spectral resolution. The second image has a second spatial resolution which is lower than the first spatial resolution and a second spectral resolution higher than the first spectral resolution. The first image and the second image are fused (216) to initialize a fused image having the first spatial resolution and the second spectral resolution. A blurring function is used (220) to help form the fused image.
