Fusion Of Remote Sensing Images via Lattice Filters

Abstract

A new image fusion algorithm based on the subband decomposition of the source images using 2-D separable lattice filters is presented. The method is used for the fusion of multispectral and SAR data. The source images are decomposed into subband images using separable lattice filters, these images are combined in the subband domain using a predefined rule, then the fused image is obtained by the inverse lattice filter.
