Paper Abstract

Modulation transfer function (MTF) is applied to the high frequency modulation fusion in this paper. Firstly, MTFs are calculated using the edge method, and 2-dimension MTF-filters are properly designed. Secondly, MTF-filters are used for degrading original high resolusion images. High frequency modulation fusion parameters are then obtained under the minimum mean square error criterion. The results show that fusion images derived from the improved high frequency modulation based on MTF method have spatial resolution close to non-degraded pan images. Compared with fusion methods of weighted high-pass filtering (w-HPF), MTF general image fusion framework (MTF-GIF), the improved method performs well in terms of preservation of spectral information and spatial resolution.
