Document Summary
Chapter 10: perceiving depth & size: oculomotor cues, monocular cues to depth perception, binocular cues to depth perception, physiology of binocular vision, perceiving size, visual illusions (failures of size constancy) Depth cues: what is a cue" to depth, think of the image on the retina. Monocular (pictorial) cues: cues to depth that you can depict in a picture, occlusion or interposition. Binocular depth information: binocular disparity: the difference in the positions of images in the two eyes. This difference provides a depth cue called stereopsis. It was believed that objects and features were used for matching: julesz random dot stereograms showed that this isn"t always true. Your text book says that there is no satisfactory answer, especially for rds patterns: however, there"s evidence that people match clusters of dots, that form a type of feature. This feature or blob is not related to the final form of the 3d object, but it can guide the computation of binocular disparity.
