The XIONG algorithm is one of the most powerful for overcoming the spectraldistortion inherently present in the Landsat panchromatic band. It requires a bitmore processing time, but for many images the result will be worth the effort.73
28. XIONG Algorithm – Automatic Method________________________________________________________________As with ENHG processing, the same XIONG process that is described above canbe performed in a single automatic step that both computes the XIONG imageand then uses it to pan sharpen the band files. In order to do this simply openthe three RGB band files, the NIR file and the panchromatic file in this order:• band1 (blue)• band2 (green)• band3 (red)• band 4 (panchromatic)• band 5 (NIR)IMPORTANT NOTE: You must open the files in the specified order or an errormessage will result.Now select ‘Pan Sharpening’ | ‘HSI Transform’ | ‘XIONG Five File (AutomaticMethod)’. PANCROMA TM will automatically compute the XIONG file and thenuse it to pan sharpen the band files. You can use the full array of imageprocessing utilities, the same as if you were processing the standard four files.IMPORTANT NOTE: When interpolating using the bilinear method and XIONGpan sharpening, the Laplacian check box will be checked and you will have theoption to input Laplacian iterations. This is for the NIR band interpolation that isused for XIONG. The default number is 40, which you can increase or decreaseto get a better NIR band interpolation. See Section 25 on the XIONG method formore information.74
