ERDAS Imagine Satellite Image Fusion (pan sharpening) using HPF (Improve Spatial Resolution)
This video tutorial helps to perform image fusion with HPF using ERDAS Imagine.
Image fusion means the combining of two images into a single image that has the maximum information content without producing details that are non-existent in the given images.
“Pan Sharpening” is shorthand for “Panchromatic sharpening”. It means using a panchromatic (single band) image to “sharpen” a multispectral image. In this sense, to “sharpen” means to increase the spatial resolution of a multispectral image.
