Source: Roughness_calculation.java

Installation: Download Roughness_calculation.class to the plugins folder and restart ImageJ.

Description: This plugin calculates surface roughness statistics based on a topographical images. The input is an image or stack in which the pixel values represent distance, z, to a surface.
The calculated roughness values are:

Ra: Arithmetical mean deviation
Rq: Root mean square deviation
Rku: Kurtosis of the assessed profile
Rsk: Skewness of the assessed profile
Rv: Lowest valley (given by the min measurements)
Rp: Highest peak (given by the max measurements)
Rt: The total height of the profile
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.
