    • Area Dominates Edge in Pointillistic Colour 

      Koenderink, Jan; van Doorn, Andrea; Gegenfurtner, Karl (2018)
      In Pointillism and Divisionism, artists moved from tonal to chromatic palettes, as Impressionism did before them, and relied on what is often called optical mixture instead of stirring paints together. The so-called optical ...

    • Eidolons: Novel stimuli for vision research 

      Koenderink, Jan; Valsecchi, Matteo; van Doorn, Andrea; Wagemans, Johan; Gegenfurtner, Karl (2017)
      Meanings and qualities are fundamental attributes of visual awareness. We propose eidolons as a tool for establishing equivalence classes of appearance along meaningful dimensions. The eidolon factory is an algorithm ...

    • Graininess of RGB-Display Space 

      Koenderink, Jan; van Doorn, Andrea; Gegenfurtner, Karl (2018)
      RGB-display space, that is, the RGB-cube, was sampled at 3,000 locations, uniformly and randomly distributed. Fifty observers contributed 60 samples each. At each location, participants synthesised a copy of the target, ...

    • Prediction shapes peripheral appearance 

      Valsecchi, Matteo; Koenderink, Jan; van Doorn, Andrea; Gegenfurtner, Karl R. (2018)
      Peripheral perception is limited in terms of visual acuity, contrast sensitivity, and positional uncertainty. In the present study we used an image-manipulation algorithm (the Eidolon Factory) based on a formal description ...

    • Seeing through transparent layers 

      Dövencioglu, Dicle N.; van Doorn, Andrea; Koenderink, Jan; Doerschner, Katja (2018)
      The human visual system is remarkably good at decomposing local and global deformations in the flow of visual information into different perceptual layers, a critical ability for daily tasks such as driving through rain ...

    • View From Outside the Viewing Sphere 

      Koenderink, Jan; van Doorn, Andrea; Pepperell, Robert (2018)
      The viewing sphere, as defined by Euclid and explored by Gibson as the optic array, is generally thought of as wrapped around the eye. Can an observer step out of it? With currently popular photographic techniques, the ...
