1. How do autostereograms differ from normal stereograms?

  • The picture is varied rather than repeated
  • The two pictures are superimposed rather than adjacent
  • The two pictures are adjacent rather than superimposed
  • The picture is repeated rather than varied

2. What is panums fusion area?

  • A narrow region on the horopter where targets falling on corresponding points are fused into a SINGLE image at a depth other than the horoper
  • A narrow region on the horopter where targets falling on NON-corresponding points are fused into a SINGLE image at a depth other than the horoper
  • A narrow region on the horopter where targets falling on NON-corresponding points are fused into TWO images at a depth other than the horoper
  • A narrow region on the horopter where targets falling on corresponding points are fused into TWO IMAGES at a depth other than the horoper

3. How do disparity-selective cells operate?

  • The seperation between the receptive field centers (relative to the fovea of each eye) of binocular cells in each eye defines the V1 cells preferred disparity
  • The disparity between the receptive field centers (relative to the fovea of each eye) of binocular cells in each eye defines the V5 cells preferred disparity

4. What is the horopter?

  • The locus of all points in 3d space that fall on corresponding retinal points
  • Both of these
  • An imaginary curved surface that passes through the fixation point

5. How do autostereograms demonstrate disparity-selectivity?

  • The picture appears superimposed with itself with an offset, the cells find matches in nearby repeated patterns. To view the image as 3D, eyes must converge at a diff plane of depth to the picture.
  • The two images are adjacent, the cells find matches in nearby repeated patterns. To view the image as 3D, eyes must converge at a diff plane of depth to the picture.
