Abstract
In this paper we present an investigation into visually perceived surface roughness. First we present psychophysical evidence that suggests that there is a simple relationship between perceived roughness and two well known surface parameters:
fractal dimension and rms roughness. And that neither are good estimators, on there own, of perceived roughness. Second we present a measurement model
for deriving the perceived roughness of a surface from its height function which is
motivated by the spatial frequency channel model of the human visual system.
