Gram-Schmidt based spectral pansharpening is a well-known scheme for fusion of panchromatic (PAN) and multispectral (MS) images. However, it relies more on the relative spectral responses between the PAN and MS sensors, which may easily suffer from spectral distortions. To deal with this problem, we present a new Gram-Schmidt based pansharpening method using guided filtering to improve the sharpened quality. The spatial information of PAN image including details and structures are effectively extracted through guided filtering and then injected into the MS imagery. The experiment is carried out on GeoEye-1 satellite images. Visual and objective analysis show that our method can produce high-quality pansharpened results and outperform some existing methods.
