Comparison of Hyperspectral and high Spatial Resolution Multispectral Image Fusion Methods of Zhuhai-1
摘要
Abstract
Enriching the spatial details information of Zhuhai-1 OrbitaHyperSpectral(OHS)images is conducive to expanding the application field of OHS data.We used six fusion methods to perform super-resolution fusion experiments between OHS data and five multi-spectral remote sensing images with high spatial resolution,and carried out the comprehensive evaluation and analysis.The experimental results show that GSA,CNMF,HySure have better spatial fidelity,and the classification results of fused images also perform better.MTF-GLP performs better in spec-tral fidelity.FUSE is greatly affected by the input data and exhibits instability,often leading to spectral distortions.MAP-SMM shows deficien-cies in experiment,with relatively poor fusion results.The running time of CNMF,HySure,MAP-SMM,and FUSE is longer compared with GSA and MTF-GLP.In addition,the smaller the time interval between the fused image sets,the better the fusion results.The quality of input images also affects the stability of fusion methods.This study provides a reference for OHS data in fusion methods and further application research.关键词
