![]() ![]() For example, in Edaphology, the transformation of a sample soil image to the Munsell soil-color charts (MSCCs) is required to identify the taxonomy and characteristics of the soil in geographical areas (Sánchez-Marañón et al., 2005 Domínguez Soto et al., 2018 Ibáñez-Asensio et al., 2013). The transformation from RGB to Munsell color space is a relevant issue for different tasks that require applying the conversion to images taken from traditional cameras or smartphones. Figure 1 shows one of the seven charts of the USA2000 version. Each chart has multiple color chips originating from the degrees of luminance and purity of color known as value and chroma. There are several versions, but each is composed of a subset of charts representing a different hue in the Munsell space. ![]() The Munsell soil-color charts (MSCCs) are derived from the Munsell space color and represent a part of the Munsell hue spectrum. ![]()
