    Franz Faul
    Institut fur Psychologie, Universitat Kiel, Germany
    J Opt Soc Am A Opt Image Sci Vis 19:1084-95. 2002
    ..These results show that the color relations leading to the perception of a homogeneous transparent layer conform very closely to the predictions of the new model and deviate systematically from the predictions of the additive model...

    Franz Faul
    Institut fur Psychologie, Christian Albrechts Universitat Kiel, Kiel, Germany

  4. doi request reprint Color appearance: The limited role of chromatic surround variance in the "gamut expansion effect"
    Franz Faul
    Institut fur Psychologie, Universitat Kiel, Germany
    J Vis 8:30.1-20. 2008
    ..These findings, particularly the latter, argue strongly against an explanation solely in terms of contrast adaptation. We suggest that the main features of our findings can be explained in terms of color scission...
  5. doi request reprint Disparity, motion, and color information improve gloss constancy performance
    Gunnar Wendt
    Institute of Psychology, Kiel, Germany
    J Vis 10:7. 2010
    ..The lightness matching data only revealed an influence of motion and color information. Our results indicate, somewhat counterintuitively, that motion information has a detrimental effect on lightness constancy...
  6. ncbi request reprint The peculiar nature of simultaneous colour contrast in uniform surrounds
    Vebjørn Ekroll
    Institut fur Psychologie, Christian Albrechts Universitat zu Kiel, Olshausenstr 62, 24118 Kiel, Germany
    Vision Res 44:1765-86. 2004
    ..A framework that systematises the seemingly complex colour appearance changes induced by uniform surrounds is presented and its implications are discussed...

    Vebjørn Ekroll
    Institut fur Psychologie, Christian Albrechts Universitat zu Kiel, Olshausenstr 62, 24098 Kiel, Germany
    Vision Res 51:311-22. 2011
    ..It is suggested that this putatively common mechanism of 'crispening' accounts completely for the gamut expansion effect, and partially for the simultaneous colour contrast effect, which seems to depend on von Kries adaptation also...
  8. doi request reprint Basic characteristics of simultaneous color contrast revisited
    Vebjørn Ekroll
    University of Kiel, Institute of Psychology, Kiel, Germany
    Psychol Sci 23:1246-55. 2012

    Institut fur Psychologie, Christian Albrechts Universitat zu Kiel, Kiel, Germany
    J Vis 8:31.1-22. 2008

    Spat Vis 19:193-218. 2006
    ..Most of our findings are consistent with the idea of sensory persistence, and indicate that information fragments are integrated over a time window of about 100 to 180 ms to form a complete surface representation...
  13. doi request reprint Transparency perception: the key to understanding simultaneous color contrast
    Vebjørn Ekroll
    Institut fur Psychologie, Universitat Kiel, Kiel, Germany
    J Opt Soc Am A Opt Image Sci Vis 30:342-52. 2013
    ..Here, we show that the revised laws of simultaneous color contrast are well accounted for by an alternative theory explaining the simultaneous contrast effect in terms of mechanisms subserving the perception of transparent media...

    Gunnar Wendt
    Department of Psychology, Kiel, Germany
    J Vis 8:14.1-10. 2008
    ..The presence of highlight disparity lead to an enhancement of both the authenticity and the strength of perceived glossiness. The latter finding was confirmed in an additional matching experiment...

    Institut fur Psychologie, Christian Albrechts Universitat, Kiel, Germany
    Percept Psychophys 64:945-55. 2002
    ..This additive model correctly predicted which combinations of colors would lead to optimal impressions of transparency. Color combinations deviating slightly from the additive model also looked transparent, but less convincingly so...
