基于局部差异加权的遥感影像融合方法研究

A New Method Based on Local Difference Powering for Remote Sensing Image Fusion

在分析现有遥感影像融合方法的基础上,针对多源遥感影像之间的地物差异,提出了一种基于局部差异加权的融合方法(local difference powering fusion,LDPF)。实验表明,该方法能在提高空间分辨率和保持光谱特征的同时,较好地解决空间信息差异的问题。

Through analyzing current methods for remote sensing image fusion, a new fusion method based on local difference powering is proposed. This method is designed for the fusion of different features in the multi-source images. The experiment shows that this method can not only maintain the spectrum characteristics and improve the spatial resolution, but also solve the problem due to the difference of spatial information.
