The calculated roughness values are:
The plugin can be used in combination with the facet Orientation plugin (Bob Dougherty, www.optinav.com/ImageJplugins/Facet-Orientation.htm) in order to get a complete assessment of the surface topography.
- Ra: Arithmetical mean deviation
- Rq: Root mean square deviation
- Rku: Kurtosis of the assessed profile
