【摘要】 在分析几种IHS算法的基础上,提出了一种适合于高分辨率遥感影像的自适应加权融合算法。该算法基于快速IHS变换,从亮度成份构成和空间细节注入程度两个方面加以改进,采用相关系数来调整权重,避免了人工指定权重带来的主观因素偏差,在提高影像空间细节和光谱保持之间取得了较好的均衡,同时还具备了高计算效率。通过融合实验并与几种改进的IHS算法的对比分析,该算法均优于其他几种改进算法。更多还原

【Abstract】 This paper tries to propose an adaptive fusion algorithm suited to high-resolution remote sensing image,which is based on the analysis of some other improved algorithm of Intensity-Hue-Saturation(IHS.)On account of fast intensity-hue-sat-uration(FIHS) transformt,his algorithm is improved from the aspects of intensity component and spatial information,and ad-justs the weight through correlation coefficient to avoid the deviation caused by the subjective factorst,herefore keeps the bal-ance between spatial details and optical spectrum and improves the calculative efficiency.Comparing with some other im-proved algorithms of IHSt,his algorithm is better than them.更多还原
