Intelligent Information Systems and Image Processing: A Novel Pan-Sharpening Technique Based on Multiscale Decomposition.

Pansharpening is a technique belong to the image fusion field, the main goal of pansharpening is to enhance the Spatial resolution of multi-spectral image while preserving the spectral resolution. In this paper a simple pan-sharpening technique using saliency detection based on a guided filter is presented. In this technique the guided filter is used to build saliency detection algorithm. The saliency can be identified by making a saliency map that can be an outstanding part of the salient information of the image. we evaluate our technique by using some real and degraded data-sets then compare our technique with some existing methods in both subjective and objective aspects. The experimental results show that the proposed strategy can accomplish magnificent execution in both subjective and objective aspects.
