Texture borders block brightness filling-in, reducing perceived brightness based on spatial frequency. This indicates brightness information spreads mainly between neurons with similar spatial frequency tuning.

Area of Science:

  • Visual perception
  • Neuroscience
  • Computational vision

Background:

  • Brightness filling-in is a visual phenomenon where perceived brightness spreads across uniform surfaces.
  • Luminance changes are known to modulate brightness filling-in.

Purpose of the Study:

  • To investigate if texture borders can disrupt brightness filling-in.
  • To determine the characteristics of brightness spreading, specifically its dependence on spatial frequency and texture orientation.

Main Methods:

  • Psychophysical measurements of perceived brightness of a uniform disk segmented by textures.
  • Systematic variation of texture spatial frequencies and orientation differences.

Main Results:

  • Texture borders significantly reduced the perceived brightness of the central disk area.

  • Brightness reduction was dependent on the spatial frequency of the textures, but not their orientation difference.
  • The bandwidth of brightness spreading was estimated to be approximately 1.5 octaves.

    • Conclusions:

    • Texture borders act as barriers to brightness filling-in.
    • Brightness information appears to spread primarily between neurons with similar spatial frequency preferences.
    • This suggests a spatial frequency-tuned mechanism underlies brightness spreading.
