    • Effects of surface reflectance and 3D shape on perceived rotation axis 

      Doerschner, K.; Yilmaz, O.; Kucukoglu, G.; Fleming, R. W. (Association for Research in Vision and Ophthalmology, 2013)
      Surface specularity distorts the optic flow generated by a moving object in a way that provides important cues for identifying surface material properties (Doerschner, Fleming et al., 2011). Here we show that specular flow ...
    • Rapid classification of surface reflectance from image velocities 

      Doerschner, Katja; Kersten, D.; Schrater P. (Springer, Berlin, Heidelberg, 2009)
      We propose a method for rapidly classifying surface reflectance directly from the output of spatio-temporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute ...
    • Seeing through transparent layers 

      Dövencioğlu, Dicle N.; Van Doorn, A.; Koenderink, J.; Doerschner, Katja (Association for Research in Vision and Ophthalmology, 2018)
      The human visual system is remarkably good at decomposing local and global deformations in the flow of visual information into different perceptual layers, a critical ability for daily tasks such as driving through rain ...
