Panchromatic and Multispectral Image Fusion Method Based on Nonsubsampled Contourlet Transform
摘要
Abstract
A novel panchromatic and multi-spectral image fusion method based on non-subsampled Contourlet Transform(NSCT) was proposed for the purpose of improving spatial and spectral resolution of remote sensing images.Firstly,HIS transformation was applied in multi-spectral image for getting its intensity component.Then,NSCT was used both in the intensity component of multi-spectral image and panchromatic image in order that the high frequency and low frequency coefficients were acquired.Furthermore,pulse-coupled neural network (PCNN) and the weighted fusion were used in the high and low frequency coefficients independently.Finally,inverse HIS transform and inverse NSCT were applied to get the fusion image.The experiment results show that many contrast experiments were made.In conclusion,space resolution and information amount of the fused image were both greatly improved.关键词
