| 摘 要： | 在分析亮度一色度-饱和度(IHS)变换影像融合方法的基础上,针对IHS变换存在光谱特征扭曲的局限性,提出了一种采用分辨率退化模型的基于IHS变换的局部回归分析融合方法.采用SPOT的全色影像和TM的多光谱影像为实验数据,经多个统计参数的定量分析以及Matlab仿真实验的验证表明,该方法在空间分辨率和光谱分辨率上都达到了较好的效果.

| Abstract: | Based on the analysis of image fusion method of IHS transform and aiming at the limitations of spectrum features distortion to IHS transform,a local regression analysis fusion based on IHS transform was proposed,which adopted a model of resolution degradation.The experiments on SPOT panchromatic images and TM multi-spectral images were carried out.The quantitative analysis by multi-statistic parameters and Matlab simulation show that this method can achieve a better effect on spatial resolution and spectrum... |
