Brightness induction by local contrast and the spatial dependence of assimilation

  title={Brightness induction by local contrast and the spatial dependence of assimilation},
  author={R. Clay Reid and Robert Shapley},
  journal={Vision Research},
Two mechanisms of brightness perception (1) brightness induction by local contrast and (2) assimilation, were examined for a variety of visual stimuli. Local contrast is the primary determinant of brightness perception, making objects appear brighter on a background of lower luminance and darker on a background of greater luminance. Assimilation is the opposite effect, whereby objects on a brighter (but not necessarily more luminant) background appear brighter or on a dark background appear… CONTINUE READING
