The notation 1/G is usually used to relate values that are linearly proportional to the surface roughness. A total of 72 3D surfaces are scanned for each grade. Since there are five grades evaluated in this study, the acquisition gives a total of 280 surfaces. A surface roughness algorithm is applied to the collected 3D surfaces. 1 lists the surface roughness and its standard deviation for each abrasive grade. The standard deviation represents the measurement precision. As listed in this table, the surface roughness increases proportionally to 1/G.

To prove that the algorithm is invariant to the rotation of the measured surface, the repeatability of the successive scans with rotation angles is evaluated. The definition of repeatability is a closeness between independent results that are obtained through the same method on an identical object, same operator, same conditions, and performed in a short time interval [36]. The absolute differences between the two measurements are used to determine the system repeatability. The repeatability itself can be accepted if 95% of the absolute measurement differences are less than two standard deviations of the measurement difference (2σDiff), as suggested by Bland and Altman [37].

40] applied FCM clustering to the lip from face skin. Color and shape information are used to classify lip from non-lip regions. Chahir and Elmoataz [41] applied FCM clustering to differentiate and segment skin regions. Color information is selected as the classification feature. The algorithm is useful for data mining purposes. Zhou et al. [42] proposed an improved FCM, anisotropic mean shift based fuzzy c-means (AMSFCM). It is used to find the lesion boundary of malignant melanoma in dermoscopy images.
