Abstract: A method of image fusion based on IHS transform and lifting quincunx wavelet transform is presented and it is applied in the fusion of multispectral image and panchromatic image. The multispectral image is transformed by IHS transform, multi-resolution lifting quincunx wavelet decomposition of the value component of multispectral image and panchromatic image is performed. Different fusion algorithms are used to the high-frequency parts and the low-frequency part. The fusion result image is obtained by lifting quincunx reconstruction and inverse IHS transform. The fusion performance of the fusion method is evaluated using objective index. The experimental results show that this method has good visual effectiveness in the preservation of spectral quality and spatial resolution information. This fusion method can preserve good spectral information and get more information from the source images. Moreover it can also preserve higher spatial resolution information. It’s fusion algorithms and the selection of decomposition level are simple and effective for multispectral image fusion.
