    • Context-dependent lightness affects perceived contrast 

      Pamir, Z.; Boyaci, H. (Elsevier Ltd, 2016)
      Perceived contrast of a grating varies with its background (or mean) luminance: of the two gratings with the same photometric contrast the one on higher luminance background appears to have higher contrast. Does perceived ...
    • The effect of context-dependent lightness on contrast detection and identification, and its neural correlates 

      Karatok, Zahide Pamir (Bilkent University, 2017-11)
      Perceived contrast of a grating varies with its background (or mean) luminance: of the two gratings with the same photometric contrast the one on higher luminance background appears to have higher contrast. On the other ...
    • Effect of contiguity and figure-ground organization on the area rule of lightness 

      Boyaci, H.; Şimşek, M. K.; Subaşı, E. (Association for Research in Vision and Ophthalmology, 2014)
      In a simple two-dimensional (2D) display composed of two uniform surfaces with different luminances, the lightness of the darker surface varies as a function of its relative area while its luminance is held constant ...
    • Perceived glossiness in high dynamic range scenes 

      Doerschner, K.; Maloney, L. T.; Boyaci, H. (Association for Research in Vision and Ophthalmology, 2010)
      We investigated how spatial pattern, background, and dynamic range affect perceived gloss in brightly lit real scenes. Observers viewed spherical objects against uniform backgrounds. There were three possible objects. Two ...
