摘要
为能同时获得空间信息与光谱信息,提出一种基于非下采样Contourlet变换(NSCT)和脉冲耦合神经网络(PCNN)的遥感图像融合算法。通过NSCT分解得到多光谱与高分辨率图像,并对其高低频分量采用不同的准则进行融合。实验结果表明,该算法能较好地保留图像光谱信息,提高图像的空间分辨率。
In order to deal with the problem that the spatial information and spectrum information are hard to be combined when remote images are fused,this paper presents a remote sensing image fusion algorithm based on Nonsubsampled Contourlet Transform(NSCT) and Pulse Coupled Neural Network(PCNN).This algorthm uses different criteria to fuse the high and low frequency components of multi-spectral and high-resolution image which are decomposed by NSCT.Simulation results show that the proposed algorithm can effectively retain the image spectral information and improve the image spatial resolution greatly.
