基于遥感影像的像素级影像融合方法比较研究

摘要

This paper first introduces four different image fusion methods in theory. Following by the qualitative and quantitative evaluation meth-ods. Then fusion experiments were conducted with the SPOT and ALOS image of Qianyingzi mine area in 2009 by using aforementioned fusion methods. From this evaluation,the paper conclude that Gram-Schmidt method is the best model in comprehensive consideration.%从理论上介绍了四种不同的融合方案算法的基本情况，以及定性和定量评价方法，再以皖北钱营孜矿区2009年的年高分辨 SPOT 影像（2.5 m）和 ALOS 多光谱影像（10 m）采用不同融合模型进行了实验，最终以灰度剖面曲线评价了融合结果，指出Gram-Schmidt 融合方法是最好的选择。
