Thispaperintroducestheimagefusionapproachofmulti-resolutionanalysis-basedintensitymodulation(MRAIM)toproducethehigh-resolutionmulti-spectralimagesfromhigh-resolutionpanchromaticimageandlow-resolutionmulti-spectralimagesfornavigationinformationinfrastructure.Themathematicalmodelofimagefusionisderivedaccordingtotheprincipleofremotesensingimageformation.Itshowsthatthepixelvaluesofahigh-resolutionmulti-spectralimagesaredeterminedbythepixelvaluesoftheapproximationofahigh-resolutionpanchromaticimageattheresolutionleveloflow-resolutionmulti-spectralimages,andinthepixelvalaecomputationtheM-bandwavelettheoryandtheàtrousalgorithmarethenused.InordertoevaluatetheMRAIMapproach,anexperimenthasbeencarriedoutonthebasisoftheIKONOS1mpanchromaticimageand4mmulti-spectralimages.TheresultdemonstratesthatMRAIMimagefusionapproachgivespromisingfusionresultsanditcanbeusedtoproducethehigh-resolutionremotesensingimagesrequiredfornavigationinformationinfrastructures.
