Computation of scale-independent surface roughness via the generation of multiscale digital elevation models

The quantitative computation of surface roughness has received increasing attention due to its importance in numerical surface study. A number of algorithms have been employed to compute surface roughness. These algorithms, which operate at singular scales of measurement, provide scale-dependant rou...
