Study Notes
Depth Perception
- When the point of fixation is closer to the eyes, the angle of convergence increases.
Stereo Vision
- The threshold for disparity judgments in stereo vision is 1-2 arcminutes.
- Binocular disparity is used in virtual reality to create depth perception.
Strabismic Amblyopia
- Uncorrected strabismus can lead to strabismic amblyopia.
- In uncorrected strabismus, binocular cortical neurons are affected.
Random Dot Stereograms
- Random dot stereograms are used to study stereo vision and depth perception.
Binocular Vision
- The purpose of binocular vision is to perceive depth.
Depth Processing
- The computational goals of depth processing are to infer depth order, depth interval, and 3D shape.
- Sensorimotor cues to depth include accommodation and motion parallax.
Visual Angle
- The measurement unit for visual angle is degrees (°).
- At a distance of 57cm, 1cm equals 1.0° of visual angle.
Atmospheric Perspective
- Atmospheric perspective is a cue to depth order and interval.
Depth Cues
- Motion parallax provides order information and can be used to infer depth order, interval, and 3D shape.
- Binocular disparity provides order information and can be used to infer depth order, interval, and 3D shape.
- Size cues involve the size of the image projected onto the retina.
Lens and Aging
- As we age, the lens becomes less flexible, affecting vision.
