Importance of pan-sharpening
• More than 70% of optical satellites simultaneously collect a low resolution MS image and a high resolution Pan image.
• Most remote sensing and GIS applications desire high resolution colour image.
• Effective and high quality pan-sharpening technique is crucial for the success of many GIS/remote sensing applications.
• Research on pan-sharpening has been conducted since the mid-1980s.

Tens of thousands papers on pan-sharpening haves been published,
only a few outstanding pan-sharpening algorithms have been adopted by industry.

Comparison among different pan-sharpening algorithmsData used for the pan-sharpening:
• IKONOS, 2002, Fredericton, Canada (Pan 540 MB, MS 135 MB)
• QuickBird, 2007, Beijing, China (Pan 820 MB, MS 205MB)
• GeoEye-1, 2009, Hobart, Australia (Pan 816 MB, MS 204 MB)
• WorldView-2, 2010, Moncton, Canada (Pan 131 MB, MS 65 MB).
All the images were in 16-bit format. All the MS bands were used in the test.

All the images are displayed under the same visualization condition, i.e.
• The same area of the images before and after pan-sharpening are displayed, and
• The same histogram stretching is applied to all the images.

Comparison conclusions
• FuzeGo produces constant best results for all type of sensors and areas.
• Other techniques work well for some images or sensors, but not for others
• The second best technique is Gram-Schmidt (Kodak’s patent). But it produces poor results for WorldView-2 images.
• The third best technique is HCS, but still result is notconsistent.
