摘要

Pansharpening has been an important technique to increase the spatial resolution of the multispectral (MS) images provided by many earth observation satellites. Since the different spatial resolutions exist between the multispectral and panchromatic (PAN) images, pansharpening usually upsamples the MS images to the same size as the PAN image and then injects the spatial details into the upscaled MS ones. In this paper, we propose a novel pansharpening method focusing on the structure injection into the MS images through a joint Gaussian guided upsampling. The original spectral information is transferred to the joint upsampling outputs by using the hyperspherical color transformation (HCT). The experimental results show that our proposed method can obtain high-quality pansharpened results and outperforms some existing methods.
