基于缨帽变换的IKONOS数据融合

Study on IKONOS data fusion based on Tasseled Cap transformation

应用缨帽变换(KT)和主成分分析(PCA)方法,对北京圆明园周围的IKONOS全色波段和多光谱波段进行融合,并分别对整景影像和植被区的融合结果进行对比研究,结果表明:在该实验区,整景影像和植被区缨帽变换融合结果都优于主成分析结果,不同的缨帽变换系数矩阵在整景影像和植被区融合质量会有差别,应根据具体地点、时相,分类方法做适当的选择。

The IKONOS data of Beijing Yuannlingyuan is fused with Tasseled Cap（KT） and PCA methods.The fusion results are analyzed and compared with full image and vegetation subset.The result shows that,in study area,the KT fusion method is better than PCA in full image and vegetation subset.The fusion results are differential with different KT transformation matrix,and the method of fusion should be chosen according to study area,data,and classification methods.
