Structured Smoothing for Superresolution of Multispectral Imagery Based on Registered Panchromatic Image

摘要

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.
