IMAGE FUSION II IKONOS HIGH SPATIAL RESOLUTION BY THE METHOD OF REPLACEMENT RGB-I1I2I3

Abstract

Data fusion according Pine et. al (2005) consists of a formal framework in which are expressed concepts and tools for merging data from different sources in order to obtain higher quality information.The fusion method has gained wide recognition when Landsat imagery, multispectral, could be combined with SPOT panchromatic images, panchromatic, and proved to be useful for generating hybrid images that combine the properties of the original images into one new image that preserves the spectral information and provides input more spatial information.This document presents the I1I2I3 method, introduced by Ohta et al. (1980), as an option fusion by replacement with the method RGBIHS.
