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.
