Abstract

A comparison of commercial Pan-sharpening techniques for HR Satellite imagery
Track: Imagery

Most of the high resolution satellites simultaneously collect high resolution panchromatic (Pan) and low resolution multispectral (MS) images in order to record the best possible spatial and spectral information of the earth's surface. Many remote sensing and GIS applications desire high resolution colour image. Therefore, an effective and high quality pan-sharpening technique is crucial for the success of many GIS/remote sensing applications. Several pan-sharpening techniques have been developed in the past and some of them have been implemented in commercial software packages. Various comparison studies have been done on these pan-sharpening techniques. However, still there is lack of a benchmark evaluation on the commercial pan-sharpening techniques. In this paper, while evaluating these pan-sharpening techniques, a common qualitative and quantitative evaluation criteria has been used on variety of image data sets. This study facilitates readers to understand the performance of each pan-sharpening technique and to select best one for their applications.
