Mottling Relevance & Mottling Curve

Because the human eye recognises mottling effects with different sensitivities, according to the size of the surface viewed, the results of the various stages are evaluated according to this factor. With flaw sizes of lower wavelengths, the human eye is relatively insensitive, because it can hardly detect such fine structures. But it is very sensitive with flaw sizes larger. The mottling score is calculated according to the flaw sizes specified in the ISO/IEC 24790 standard.
