Iconic image fusion is a technique that is used to combine the spatial structure of a high resolution panchromatic image with the spectral information of a lower resolution multispectral image to produce a high resolution multispectral image. This process is often referred to as pansharpening. In this study, image data of the new RADAR satellite TerraSAR-X are used to sharpen optical multispect...

An automatic process for relative registering and merging the panchromatic and multispectral images of SPOT5 is presented. The automated hierarchical local registration process makes use of feature information to select tie points from both images. The tie points are then used to refine the sensor model of the multispectral image by method of least squares solution. Both panchromatic and multis...

The standard data fusion methods may not be satisfactory to merge a high-resolution panchromatic image and a low-resolution multispectral image because they can distort the spectral characteristics of the multispectral data. In this paper, we developed a technique, based on multiresolution wavelet decomposition, for the merging and data fusion of such images. The method presented here consists ...

Image fusion in the field of remote sensing deals with combination of multispectral and panchromatic image. The idea of such combination is to derive best information out of it. A multispectral image is spectral rich whereas a panchromatic image is spatially sound so their combination gives better information in terms of best spatial and spectral parameters. This Paper aims at evaluating variou...

Thanks to some technical progress in interferencefilter design based on different technologies, we can finally successfully implement the concept of multispectral filter array-based sensors. This article provides the relevant state-of-the-art for multispectral imaging systems and presents the characteristics of the elements of our multispectral sensor as a case study. The spectral characteristi...
