  • The same disparity produced from a shift in depth of an object (filled coloured circles) can also be produced by laterally shifting the object in constant depth in the picture one eye sees (black circles with coloured margin). (wikipedia.org)
  • Note that for near disparities the lateral shift has to be larger to correspond to the same depth compared with far disparities. (wikipedia.org)

  • The night vision system amplifies ambient illumination and allows soldiers to see night environments that would be essentially invisible to the unaided eye. (nationalacademies.org)
  • In a working environment that is arguably the most dangerous of any current profession, image intensification and thermal imaging have extended the normal perceptual capabilities of the soldier and allowed vision to operate in conditions in which the unaided eye would be ineffective.

  • Binocular single vision (BSV) is the ability to use both eyes together to achieve a single fused percept, even in the presence of disparity of the image seen by each eye. (optography.org)
  • Image from each eye is superimposed on each other in occipital cortex to obtain binocular single vision. (optography.org)
  • Visual binocular disparity is defined as the difference between the point of projection in the two eyes and is usually expressed in degrees as the visual angle. (wikipedia.org)
  • However, in computer vision, binocular disparity is referenced as coordinate differences of the point between the right and left images instead of a visual angle. (wikipedia.org)
  • Specifically, these neurons will be active, if an object with "their" special disparity lies within the part of the visual field to which they have access (receptive field). (wikipedia.org)
  • Also called double vision, it is a loss of visual focus under regular conditions, and is often voluntary. (optography.org)
