Does Motion Parallax Improve Communication Efficiency in Video Chats?
… video chat in terms of peer communication. Motion parallax is a perceptual effect that arises when an observer moves relative to their surroundings, or their surroundings move relative to them, causing nearby objects in their visual field to appear to move more quickly than distant objects. …

Tolstoy and Zola: Trains and Missed Connections
… aspect of the railway experience, known as motion parallax, which is a depth cue that enables a person to detect depth while in motion. Stationary objects close to a travelling train appear to be moving faster than objects in the distance, such as a mountain range, and moreover they appear …

Behavioral measurements of visual processing in adult male and female hooded rats: Do visual tasks reflect sex differences in visual cortex morphology?
… functions--grating acuity, vernier acuity, and motion parallax information--that are processed in the primary visual cortex were examined. Grating acuity was measured in a forced choice Y-maze and a jumping stand. Using a criterion of 34 correct/50 trials, grating acuity for both sexes was high …

Perceived Depth in Virtual and Physical Environments
… to account for the integration of stereopsis and motion cues. I measured the perceived depth of virtual and physical objects defined by motion parallax, binocular disparity, or their combination. Accuracy was remarkedly similar for both environments, but estimates were more precise when depth was …

Active Vision Strategies in Predation
… exhibited by jumping insects, which use motion parallax, a form of active vision, to assess jump distance, suggesting darting robber flies also use motion parallax to predate. The final experimental chapter considers killer flies, Coenosia attenuata, which chase moving targets aerially. …

Neural responses to relative motion in V1 and V2 of macaque monkeys
Relative motion information is required for solving many complex visual tasks, such as depth perception by motion parallax and motion-induced figure/ground segmentation. However, little is known about the neural substrate for relative motion. To explore the neural mechanisms underlying relative …

Holographic television : measuring visual performance with holographic and other 3D television technologies
… focus at the expense of others), and horizontal motion parallax (depth and other geometry of objects appears natural over a range of head movement). Holographic television can also emulate other precursor 2D and 3D display technologies. This capability was used to validate the evaluation …

Visual optic flow processing for posture and 3D shape perception in primary open angle glaucoma
… that the processing of large field visual motion (optic flow) information is critical for postural control and 3-dimensional (3D) shape perception. Histopathological and psychophysical studies support the view that primary open angle glaucoma (POAG) preferentially damages the magnocellular …

Perceptual Cues and Subjective Organization in a Virtual Information Workspace
… depth. One of the 3D desktop conditions conveyed motion parallax through an automatic rotation. It was expected that performance would increase as the number of perceptual cues increased.</p> <p>The present study also examined the potential benefits of organizing and retrieving documents from a …

The influence of depth and stutter on consumer preference for static three-dimensional lenticular-sheet images
… induce the sensation of object depth through motion parallax and stereopsis, which is based on retinal disparity. To achieve the three-dimensional effect, some sacrifice of image quality must be made. A study is described which investigated the tradeoff between depth and image quality that is …

Image Segmentation and Range Estimation Using a Moving-aperture Lens
Given 2D images, it still remains a big challenge in the field of computer vision to group the image points into logical objects (segmentation) and to determine the locations in the scene (range estimation). Despite the decades of research, a single solution is yet to be found. Through our research …
