1. A method for creating a fused image from an image pair comprising a panchromatic image and a multi-spectral image, comprising: obtaining image data defining a first image of a panchromatic image type, said first image having a first spatial resolution and a first spectral resolution; obtaining image data defining a second image of a multi-spectral image type, said second image having a second spatial resolution lower than said first spatial resolution and a second spectral resolution higher than said first spectral resolution; fusing said first image and said second image to initialize a fused image having said first spatial resolution and said second spectral resolution; and blurring at least one pixel comprising said fused image based on radiance values of at least one pixel comprising said first image.
