BAYESIAN SUPER-RESOLUTION PANSHARPENING USING CONTOURLETS

摘要

Pansharpening is a technique that fuses a low resolution multispec-tral image and a high resolution panchromatic image, to obtain a multispectral image with the spatial resolution and quality of the panchromatic image while preserving spectral information of the multispectral image. In this paper, we present a new pansharpening method based on super-resolution and contourlet transform. The ex-perimental results show that the proposed method not only enhances the spatial resolution of the pansharpened image, but also preserves the spectral information of the original multispectral image.
