Abstract The fusion methods such as IHStransform could merge two sorts of optical image data with different resolutions-a high spatial resolution panchromatic image and a low spatial resolution multispectral image. Nevertheless, such fusion methods require that the spectral response range of the high spatial resolution panchromatic image is identical or approximates to the spectral response range of the multispectral image. This paper puts forward a new fusion method called high-pass filter fusion (HPFF) that could merge two sorts of optical image data with different spectral characteristics. Its algorithm is as follows: First, to filter on the panchromatic image with high pass filter, and then to fuse the remote sensing data by applying IHStransformation. The color of the HPFFimage approximates to the color of multispectral image. The HPFFmethod is more effective in spectral preservation than the IHStransformation.
