在分析几种改进IHS算法的基础上,针对IKONOS影像融合后植被区出现的色偏问题,提出一种改进算法。该算法采用缨帽变换的方法提取植被信息,并对植被区与非植被区分别采用不同的融合策略,最终得到融合影像。实验结果表明,该算法在保持光谱和提高空间细节之间获得较好均衡的同时,植被区的色偏问题也得到改善,具有更好的目视效果,与几种改进的IHS算法对比分析,该算法均优于其他几种改进算法。 更多还原

【Abstract】 This paper proposes an improved algorithm,which is dealing with the color distortion problem of the vegetation region after the IKONOS image fusion,based on the analysis of some other improved algorithms of Intensity-Hue-Saturation(IHS).The proposed algorithm adopts the method of Tasseled Cap Transform to extract the vegetation information and employs the different fusion strategies to analyze the vegetation region and non-vegetation region separately in order to get a final fused image.Experime... 更多还原
