摘要

提出了一种基于点阵滤波和空间频率的ERS和SPOT多光谱图像融合算法。首先，采用分析点阵滤波结构对ERS和SPOT数据进行子带分解。将详细子带分解成块，并根据预定义的基于空间频率的规则对这些块进行合并。最后，通过合成点阵滤波结构得到融合图像。

A new subband domain method for spatial frequency based image fusion

A new image fusion algorithm, based on lattice filters and spatial frequency, to merge ERS and multispectral SPOT data is presented. First, ERS and SPOT data are decomposed into their subbands with analysis lattice filter structure. The detail subbands are decomposed into blocks, and these blocks are merged according to a predefined Spatial Frequency based rule. Finally, the fused image is obtained by synthesis lattice filter structure.
