GUI-based HighView framework
GUI-based HighView adopts a comprehensive image fusion workflow which includes three steps - band combination, pan-sharpening, and assessment. To operationalise them, HighView contains a series of analytical modules (Figures 1 and 2).
- Band combination: Prepares low-resolution natural or false colour composites, which can be used to compare with pan-sharpened results;
- Pan-sharpening: Forms the core of our image fusion program. HighView's single step pan-sharpening incorporates four efficient optimisation methods, and a number of spatial and spectral enhancement options; and
- Assessment: Includes both visual and quantitative appraisals. Three convenient tools are provided for facilitating quantitative assessments.

| GUI-based HighView reads 8- or 16-bit generic image
matrices (raw raster data), including ENVI's *.img/*.hdr
format and Idrisi32's *.rst/*.rdc format. Images
in GeoTIFF format from major image vendors are
also supported. The main window of HighView is a log file editor, displaying progress information of individual runs. |
