3.21 Perception/decoding: Edges, contrasts and colors

  • Our visual system is attracted to edges, and we assess contrast and brightness in terms of relative rather than absolute values (Healy 2018, Ch. 1.3.1)
  • Our ability to see edge contrasts is stronger for monochrome images than for color (Healy 2018, Ch. 1.3.1)
