一种基于IHS圆柱变换模型的影像融合质量综合评价方法

影像融合在遥感影像分析和处理中有着广泛的应用,而针对影像融合的质量评价亦已成为国内外的研究热点.在现有的融合评价算法中,大部分定量评价指标没有统一的评价基准,无法同时对融合影像的空间特性和光谱特性这一对矛盾特性进行综合评价.本文采用与传统方法不同的思路,在分析常用融合模型的基础上,经理论推导得到一种“基于IHS圆柱变换...

A method based on IHS cylindrical transformation model for quality assessment of image fusion

Image fusion techniques have been widely applied to remote sensing image analysis and image processing,and methods for quality assessment of image fusion in remote sensing have also become the research issues at home and abroad.But in the existing assessment methods,there is not a uniform standard for most of the quantitative assessment indexes,and the spatial resolution and spectral characteristic could not be analyzed synchronously by these indexes.So in this paper,on the basis of analysis of the model of traditional fusion algorithms,a correlation coefficient assessment method based on IHS cylindrical transformation was proposed.By experiments,this method could not only get the evaluation results of spatial and spectral features on the basis of uniform standard,but also acquire the comparison between fusion image sources and fusion images,and differences among fusion algorithms.Compared with the traditional evaluation methods,the new methods would be more intuitionistic,and in accord with subjective estimation.
