  annote = {We report results from a new methodology for investigating
    the visually perceived properties of surface textures. Densely
    sampled two-dimensional 1/f^beta-noise processes are used to
    model natural looking surfaces, which are rendered using combined
    point-source and ambient lighting. Surfaces are shown in motion to
    provide rich cues to their relief. They are generated in real time
    to enable observers to dynamically manipulate surface
    parameters. A method of adjustment is employed to investigate the
    effects that the two surface parameters, magnitude roll-off factor
    and RMS height, have on perceived roughness. The results are used
    to develop an estimation method for perceived roughness.},
