  2. Autostereogram - Wikipedia

    en.wikipedia.org/wiki/Autostereogram

    When the single 2D image is viewed with proper eye convergence, it causes the brain to fuse different patterns perceived by the two eyes into a virtual 3D image without, hidden within the 2D image, the aid of any optical equipment. SIS images are created using a repeating pattern. [18] [29] Programs for their creation include Mathematica. [30] [31]

  3. Binocular disparity - Wikipedia

    en.wikipedia.org/wiki/Binocular_disparity

    Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes' horizontal separation ().The mind uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis.

  4. Depth perception - Wikipedia

    en.wikipedia.org/wiki/Depth_perception

    The convergence will stretch the extraocular muscles – the receptors for this are muscle spindles. As happens with the monocular accommodation cue, kinesthetic sensations from these extraocular muscles also help in distance and depth perception. The angle of convergence is smaller when the eye is fixating on objects which are far away.

  5. 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.

  6. 2D to 3D conversion - Wikipedia

    en.wikipedia.org/wiki/2D_to_3D_conversion

    2D to 3D video conversion (also called 2D to stereo 3D conversion and stereo conversion) is the process of transforming 2D ("flat") film to 3D form, which in almost all cases is stereo, so it is the process of creating imagery for each eye from one 2D image.

  7. Stereopsis - Wikipedia

    en.wikipedia.org/wiki/Stereopsis

    The cube is shifted to the right in left eye's image. The cube is shifted to the left in the right eye's image. We see a single, Cyclopean, image from the two eyes' images. The brain gives each point in the Cyclopean image a depth value, represented here by a grayscale depth map.

  8. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    The visual system performs a number of complex tasks based on the image forming functionality of the eye, including the formation of monocular images, the neural mechanisms underlying stereopsis and assessment of distances to (depth perception) and between objects, motion perception, pattern recognition, accurate motor coordination under visual ...

  9. Convergence micropsia - Wikipedia

    en.wikipedia.org/wiki/Convergence_micropsia

    Convergence micropsia is a type of micropsia characterized by the reduction in apparent size of objects viewed when the eyes are more converged than they need to be for the distance of the object from the eyes. [1] [2] [3] It occurs mainly during stereoscopy and when viewing autostereograms (such as Magic Eye pictures).
