The fusion algorithms of remote sensing images based on multiresolution analysis

给出了一种基于非抽样Contourlet变换的遥感图像融合算法.根据分解后不同层次的特点采用不同的融合规则,对高频分量采用区域能量的融合规则,使得融合图像的光谱质量和空间质量得到均衡提高,实验表明,该算法可以更好地表现高分辨率全色图像的细节特征,同时在保持多光谱图像的光谱信息方面具有较大优势.

An algorithm of nonsubsampled contourlet transform based for remote sensing image fusion was proposed.Different rules were adopted based on different decomposed levels,the rule of local energy had anadvantage in choosing coefficients of high frequency which improved the spectral qualities and the space resolution quality at the same time.The experimental results demonstrated that the proposed approach outperforms the other traditional methods in the spectral.
