    Rapid classification of specular and diffuse reflection from image velocities
    (Elsevier BV, 2011-09) Doerschner, K.; Kersten, D.; Schrater, P. R.
    We propose a method for rapidly classifying surface reflectance directly from the output of spatiotemporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute histograms of image velocities and classify these as being generated by a specular or a diffusely reflecting object. Exploiting characteristics of material-specific image velocities we show that our classification approach can predict the reflectance of novel 3D objects, as well as human perception.
