Texture Module Parameters

Index Name / Title Unit Description
60° 60° Gloss GU Conventional 60° gloss value of the textured area, indicating overall specular reflectance level.
Sa Rough Areal Surface Roughness p‑µm Average height variation over the measured area using unfiltered topographical data, expressed in perceived microns.
Ca Cell Altitude p‑µm Average height of texture “cells” (features) relative to the local mean plane.
Cn Cell Number – Total number of detected texture cells within the analysed area.
Cs Mean Cell Size p‑µm Average lateral size of the detected texture cells.
CsMin Minimum Cell Size p‑µm Smallest detected cell size within the measurement area.
CsMax Maximum Cell Size p‑µm Largest detected cell size within the measurement area.
CsDev Cell Size Standard Deviation p‑µm Variation (spread) of cell sizes, indicating how uniform the texture features are.
Hs Hill Size p‑µm Typical size of raised “hill” features on the surface.
F Fill Factor – Fraction of the area occupied by detected texture cells or hills.
R Reflectivity – Average reflectivity level of the textured surface region.
RC Reflective Contrast – Difference in reflectivity between texture features and surrounding areas.
RV Reflectivity in Valleys – Reflectivity associated with valley (low) regions of the texture.
RH Reflectivity on Hills – Reflectivity associated with hill (high) regions of the texture.
Fsep Feature Separation µm Records the user setting for Feature Seperation parameter
Fsel Feature Selecttion %tage Records the user setting for Feature Selection parameter analysis.
FThld Feature Threshold -1 to +1 Records the user setting for Feature Threshold parameter analysis.
R (RGB) Red RGB Colour Intensity (0–255) Average red-channel surface colour within the textured area.
G (RGB) Green RGB Colour Intensity (0–255) Average green-channel surface colour within the textured area.
B (RGB) Blue RGB Colour Intensity (0–255) Average blue-channel surface colour within the textured area.
