Computed Tomography to Estimate the Representative Elementary Area for Soil Porosity Measurements

Figure 7

Normalized frequency of the porosity by image (%) from the 5th selected area in the sample 01 (S 01). A 05, A 06, …, and A 15 correspond to the sequence of quadrangular areas selected in the image and free area (FA). GA represents the Gaussian adjustment, 𝑟 2 the coefficient of determination, and FWHM the full width at a half maximum of the curve.
