基于Quick Bird数据的遥感图像融合方法研究
THE STUDY OF DATA FUSION TECHNIQUES FOR THE QUICK BIRD REMOTELY SENSED IMAGERY
【摘要】 在分析了图像融合原理和计算方法的基础上,以QuickBird全色与多光谱遥感图像为数据源,运用HIS变换、主成分分析(PCA)和乘积变换(Brovey)3种算法,对QuickBird遥感图像进行了融合实验研究,并从光谱的真实性和空间纹理信息两个方面对融合效果进行测试与分析,比较3种算法用于处理QuickBird遥感图像的效果.研究结果表明:HIS融合的效果最佳,PCA融合的效果次之,Brovey融合的效果最差.
【Abstract】 Based on analyzing the principals and methods of Image fusion,with Multi-spectral and Panchromatic image of the Quick Bird for data source,the author tried three fusion gorithmys:HIS transformation,principal component transformation and Brovey transformation to research the Image fusion,and studies the three fusion gorithmys in terms of the spectrum quality and the interspace information of the images.The study shows:the best fusion gorithmy is HIS transformation,the second one is principal component transformation,and the last one is Brovey transformation.
