Cependant, divers paramètres affectent la perception de la vision stéréo. Dans cette thèse, une série d'expériences physiologiques ont été menées visant à évaluer la perception visuelle 3D par rapport à 3 des facteurs les plus importants: la technologie d'affichage 3D, les environnements de visualisation et de mouvement en profondeur (MID). Nous avons d'abord mesuré l'amplitude de fusion verticale (VFA) sur les projecteurs 3D et une télévision autostéréoscopique. Le VFA a été choisi comme un indicateur pour le confort visuel en raison de notre forte sensibilité à la disparité verticale. Plusieurs facteurs ont été testés (e.g. distance d'observation, la luminance du fond, la diaphonie, l'angle de vue, etc.). Nous avons comparé les performances d'observateur sur les deux écrans 3D et conclu que la tolérance pour la disparité verticale était meilleure sur le projecteur 3D que sur la télévision autostéréoscopique. Pour l'impact de l'environnement sur la perception stéréo, nous avons mesuré le VFA sur un projecteur 3D en fonction de l'éclairage de la pièce, de la complexité du contenu 3D, de la vitesse de disparité. Nous avons évalué l'interaction entre la fusion centrale et périphérique, en introduisant une série de prismes en face d'un oeil. Nous avons observé que l'équilibre de la fusion entre vision centrale et périphérique était rompu quand de grandes disparités périphériques (> 4 dioptries prismatiques) ou tailles de stimuli (angle central du stimulus

Available in PDF, EPUB and Kindle. Book excerpt: Human Factors of Stereoscopic Displays provides an overview of all vision-relevant topics and issues that inform stereo display design from a user-centric or human factor, perspective. Although both the basic vision science literature and the applied literature will be reviewed, the strength and originality of this book comes from the emphasis on the basic science literature on human stereo vision and its implications for stereo display design. The reader will learn how to design stereo displays from a human vision/human factors perspective. Over the past several years, there has been a growing interest in the development of high-quality displays that present binocular parallax information to the human visual system for inducing the perception of three-dimensional depth. The methods for presenting binocular parallax to an observer vary widely and include three broad categories of display: stereoscopic, holographic and volumetric displays. Because the technology for stereoscopic displays is more developed and more widely used, than those based on holography or volumetric methods, the proposed book addresses those human factors issues involved in the viewing of stereoscopic displays. Despite the diverse methods for creating stereoscopic displays, which includes stereo spatial multiplexing as well as temporal multiplexing (i.e., field sequential) techniques, there remain common human factor issues that arise when viewing such displays. Human Factors of Stereoscopic Displays will provide a detailed review of these important issues so that they can be considered when designing and using 3D displays. In doing so, the following topics will be covered: interocular cross talk; interocular differences in luminance and contrast; accommodation-vergence mismatch; stereoanomaly; spatio-temporal frequency effects; distance scaling of disparity and high-level cue conflict. body>

This book was released on 2012-01-27 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 2 addresses stereoscopic vision in cats and primates, including humans. It begins with an account of the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, binocular masking, and the interocular transfer of visual effects, such as the motion aftereffect and visual learning. The geometry of the region in binocular space that creates fused images (the horopter) is discussed in some detail. Objects outside the horopter produce images with binocular disparities that are used for stereoscopic vision. Two chapters provide accounts of mechanisms that bring the images into binocular register and of stimulus tokens that are used to detect binocular disparities. Another chapter discusses cyclopean effects, such as cyclopean illusions, cyclopean motion, and binocular direction that are seen only with binocular vision. Stereoacuity is the smallest depth interval that can be detected. Methods of measuring stereoacuity and factors that influence it are discussed. Two chapters deal with the various types of binocular disparity and the role of each type in stereoscopic vision. Another chapter deals with visual effects, such as figure perception, motion perception, and whiteness perception that are affected by the relative distances of stimuli. The spatiotemporal aspects of stereoscopic vision, including the Pulfrich stereomotion effect are reviewed. The volume ends with an account of techniques used to create stereoscopic displays and of the applications of stereoscopy.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the investigation of human perception of stereoscopic 3D image quality and the development of automatic stereoscopic 3D image quality assessment frameworks. In order to assess human perception of visual quality, a human study was conducted and interactions between image quality, depth quality, visual comfort, and 3D viewing quality were inferred. The results indicate that the overall 3D viewing quality can be well predicted from only image quality and depth quality. Between image and depth quality, image quality seems to be the main factor that enables accurate prediction of overall 3D viewing quality. Two other human studies were conducted to study the effect of masking on stereoscopic distortions. Binocular suppression was observed in the stereo images which were distorted by blur, JPEG compression, or JPEG2K compression, however, no such suppression was observed for stereo images distorted by white noise. Further, a facilitation effect was also observed against disparity variation for blur and JPEG2K distorted stereo images while no depth masking effect was observed. Based on these results, I proposed an automatic full-reference (FR) 3D quality assessment framework. In this framework, I used Gabor filterbank responses to model stimulus strength and then synthesize a Cyclopean image from a stereo image pair. Because the quality of this synthesized view is similar to that of a Cyclopean image, which the human visual system recreates from the stereoscopic stimuli, performing the task of 3D quality assessment on synthesized views can deliver better performance. I verified the performance of this FR framework on the LIVE 3D Image Quality Database and the results indicate that applying the proposed framework improves the performance of FR 2D quality assessment algorithms when applied to stereo 3D images. Further, I proposed a no-reference (NR) 3D quality assessment (QA) algorithm based on natural scene statistics in both the spatial and the depth domain. Experiments indicate that the proposed NR algorithm outperforms all 2D FR QA algorithms and most 3D FR QA models in predicting 3D quality of stereo images. Finally, a fourth subjective study was conducted to understand depth quality when stereo content is free from visual discomfort. The result suggests that human perception of depth quality is correlated with the content of the stereo image and the stereoacuity function of human visual system.

Book excerpt: A revelatory account of the brain's capacity for change When neuroscientist Susan Barry was fifty years old, she experienced the sense of immersion in a three dimensional world for the first time. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space. Leaves created intricate mosaics in 3D. Barry had been cross-eyed and stereoblind since early infancy. After half a century of perceiving her surroundings as flat and compressed, on that day she saw the city of Manhattan in stereo depth for first time in her life. As a neuroscientist, she understood just how extraordinary this transformation was, not only for herself but for the scientific understanding of the human brain. Scientists have long believed that the brain is malleable only during a "critical period" in early childhood. According to this theory, Barry's brain had organized itself when she was a baby to avoid double vision - and there was no way to rewire it as an adult. But Barry found an optometrist who prescribed a little-known program of vision therapy; after intensive training, Barry was ultimately able to accomplish what other scientists and even she herself had once considered impossible. Dubbed "Stereo Sue" by renowned neurologist Oliver Sacks, Susan Barry tells her own remarkable journey and celebrates the joyous pleasure of our senses.

Available in PDF, EPUB and Kindle. Book excerpt: Visual short-term memory has been studied extensively, however nearly all research on this topic has assessed two-dimensional object properties. This is unexpected, given that most individuals perceive the visual environment in three-dimensions. In the experiments reported here, I investigate the stimuli necessary to assess visual short-term memory while eliminating potential confounds: the use of verbal memory to encode visual information, and the unintentional use of mental resources directed at irrelevant aspects of the memory task. I assess the impact of the amount of disparity, and the distribution of elements in depth, on visual short-term memory. Individuals retain simple visual stimuli equivalently when information is displayed in 2-D or 3-D, regardless of how objects are distributed in 3-D. Conversely, ease of encoding does influence visual short-term memory. Tasks that facilitate encoding result in better visual short-term memory performance. The experiments reported show that stereoscopic 3-D does not improve visual short-term memory.
