  2. Stereopsis - Wikipedia

    en.wikipedia.org/wiki/Stereopsis

    Stereopsis (from Ancient Greek στερεός 'solid' and ὄψις (ópsis) 'appearance, sight') is the component of depth perception retrieved through binocular vision. [1] Stereopsis is not the only contributor to depth perception, but it is a major one.

  3. Stereoscopic acuity - Wikipedia

    en.wikipedia.org/wiki/Stereoscopic_acuity

    More than other such visual capabilities, the limits of stereopsis depend on the observer's familiarity with the situation. Stereo thresholds almost always improve, often several-fold, with training [ 8 ] and involve perceptual factors, differing in their particulars for each test. [ 9 ]

  4. Depth perception - Wikipedia

    en.wikipedia.org/wiki/Depth_perception

    Stereopsis is merely relative because a greater or lesser disparity for nearby objects could either mean that those objects differ more or less substantially in relative depth or that the foveated object is nearer or further away (the further away a scene is, the smaller is the retinal disparity indicating the same depth difference).

  5. Binocular rivalry - Wikipedia

    en.wikipedia.org/wiki/Binocular_rivalry

    Wheatstone also discovered binocular stereopsis, the perception of depth arising from the lateral placement of the eyes. Wheatstone was able to prove that stereopsis depended on the different horizontal positions (the horizontal disparity ) of points in the images viewed by each eye by creating the illusion of depth from flat depictions of such ...

  6. Chromostereopsis - Wikipedia

    en.wikipedia.org/wiki/Chromostereopsis

    Blue–red contrast demonstrating depth perception effects 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.

  7. Binocular vision - Wikipedia

    en.wikipedia.org/wiki/Binocular_vision

    To maintain stereopsis and singleness of vision, the eyes need to be pointed accurately. The position of each eye in its orbit is controlled by six extraocular muscles. Slight differences in the length or insertion position or strength of the same muscles in the two eyes can lead to a tendency for one eye to drift to a different position in its ...

  8. Stereoscopy - Wikipedia

    en.wikipedia.org/wiki/Stereoscopy

    Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.

  9. Stereopsis recovery - Wikipedia

    en.wikipedia.org/wiki/Stereopsis_recovery

    Stereopsis recovery, also recovery from stereoblindness, is the phenomenon of a stereoblind person gaining partial or full ability of stereo vision . Recovering ...
