“…In the RS discipline, there is a long history of prior knowledge-based MS reflectance space partitioners for static color naming, alternative to SIAM’s, developed but never validated by space agencies, public organizations and private companies for use in hybrid EO-IUSs in operating mode, see Figure 11. Examples of hybrid EO image pre-processing applications in the quantitative/sub-symbolic domain of information-as-thing , where a numeric input variable is statistically class-conditioned (masked) by a static color naming first stage to generate as output another numeric variable considered more informative than the input one, are large-scale MS image compositing (Ackerman et al 1998; Lück & van Niekerk, 2016; Luo, Trishchenko, & Khlopenkov, 2008), MS image atmospheric correction and topographic correction (Baraldi, 2017; Baraldi et al, 2010b; Baraldi & Humber, 2015; Baraldi et al, 2013; Bishop & Colby, 2002; Bishop et al, 2003; DLR & VEGA, 2011; Dorigo et al, 2009; Lück & van Niekerk, 2016; Riano et al, 2003; Richter & Schläpfer, 2012a, 2012b; Vermote & Saleous, 2007), see Figure 12, MS image adjacency effect correction (DLR & VEGA, 2011) and radiometric quality assessment of pan-sharpened MS imagery (Baraldi, 2017; Despini, Teggi, & Baraldi, 2014). Examples of hybrid EO image classification applications in the qualitative/equivocal/categorical domain of information-as-data-interpretation and statistically class-conditioned by a static color naming first stage are cloud and cloud-shadow quality layer detection (Baraldi, 2015, 2017; Baraldil., DLR & VEGA, 2011; Lück & van Niekerk, 2016), single-date LC classification (DLR & VEGA, 2011; GeoTerraImage, 2015; Lück & van Niekerk, 2016; Muirhead & Malkawi, 1989; Simonetti et al 2015a), multi-temporal post-classification LC change (LCC)/no-change detection (Baraldi, 2017; Baraldi et al, 2016; Simonetti et al, 2015a; Tiede, Baraldi, Sudmanns, Belgiu, & Lang, 2016), multi-temporal vegetation gradient detection and quantization into fuzzy sets (Arvor, Madiela, & Corpetti, 2016), multi-temporal burned area detection (Boschetti, Roy, Justice, & Humber, 2015), and prior knowledge-based LC mask refinement (cleaning) of supervised data samples employed as input to supervised data learning EO-IUSs (Baraldi et al, 2010a, 2010b).…”
