Multispectral and Panchromatic Image Fusion Based on NSCT and HIS Transform
NSCT (Nonsubsampled Contourlet Transform) is a multi-scale、 multi-direction method with strong sparse decomposition property, which can capture detail information of images efficiently.Considering the advantages of NSCT, the new fusion method based on NSCT and HIS (Hue-Intensity-Saturation) transform for remote sensing images is proposed.Firstly, I (Intensity) component was obtained from multispectral image through HIS transform.Then NewI coefficients were obtained by fusion algorithm, which performed on I component and Panchromatic image by NSCT transform.Finally, the fusion images were received by inverse HIS transform on H and I component of multispectral image and NewI.The experiment results show that the proposed algorithm not only preserves spectral information of original images well, but also enhances detail texture information in image fusion.
