摘要
多传感器遥感图像融合按信息表征层次的不同,可以分为像素级融合、特征级融合和决策级融合。本文介绍了像素级层次上的多种遥感图像融合方法,阐述了其融合原理和实现过程,分析了它们适用性和优缺点,并给出了遥感图像融合的一般评价指标。
According to different levels of information attribute, there are three different levels of the multi-sensor remote sensing image fusion, namely, the picture element level, characteristic level and decision-making level. This paper introduces various kinds of remote sensing image fusion method at the picture element level, elaborates the fusion principle and realization process, analyzes their applicability, advantage and disadvantage, and gives the general evaluating indexes for the remote sensing image fusion.
