  • Some aspects of visual discomfort 

    O'Hare, Louise (University of St Andrews, 2013-06-25) - Thesis
    Visual discomfort is the adverse sensations, such as headaches and eyestrain, encountered on viewing certain stimuli. These sensations can arise under certain viewing conditions, such as stereoscopic viewing and prolonged ...
  • Uncomfortable images produce non-sparse responses in a model of primary visual cortex 

    Hibbard, Paul B.; O'Hare, Louise (2015-02-25) - Journal article
    The processing of visual information by the nervous system requires significant metabolic resources. To minimize the energy needed, our visual system appears to be optimized to encode typical natural images as efficiently ...
  • Visual discomfort and blur 

    O'Hare, Louise; Hibbard, Paul Barry (2013-04-10) - Journal article
    Certain visual stimuli, such as striped patterns and filtered noise, have been reported to be uncomfortable. Some filtered noise patterns judged as uncomfortable are those with a relative decrease in contrast amplitude at ...
  • Visual discomfort and depth-of-field 

    O'Hare, Louise; Hibbard, Paul Barry; Zhang, Tingting; Nefs, Harold T. (2013) - Journal article
    Visual discomfort has been reported for certain visual stimuli and under particular viewing conditions, such as stereoscopic viewing. In stereoscopic viewing, visual discomfort can be caused by a conflict between accommodation ...
  • Visual discomfort and the spatial distribution of Fourier energy 

    Penacchio, Olivier; Wilkins, Arnold (2015-03) - Journal article
    Quite independently of what they represent, some images provoke discomfort, and even headaches and seizures in susceptible individuals. The visual system has adapted to efficiently process the images it typically experiences, ...
