Stereo vision involves deriving scene depth from the differences in two images of a scene. It is classically formulated as a matching problem, with the results of matching easily translated to scene depth. Recent research has shown that the stereo ...

This paper presents a content prioritization technique for perceptually enhanced communication of 3D video data over wireless Local Area Network. The prioritisation is performed on the basis of a novel segmentation technique, which utilizes the depth ...

Stereo video stands to revolutionize the medium of videogames in the same way that stereo sound revolutionized the audio experience. It is a pending revolution. Despite years of research, development, and hype, 3D stereo video ubiquity in videogames has ...

Because of the prevalence of digital imaging in radiology and the developments of electronic three-dimensional (3D) viewing devices, digital stereoradiography will become an efficient and economical way for improving the diagnostic efficacy. A viewing ...

Stereoscopic scenes of the mankind is naturally caused by synthesizing two images produced by the parallax of the two eyes of human. Such being the case, mankind can distinguish the relative position of the objects. In the study of related stereovision, ...

This paper reports on studies we are conducting to evaluate 3D stereoscopic rendering systems accuracy and efficiency. These studies are part of our project dealing with tele-operation, namely the use of virtual reality technology to increase immersion ...

This work adds the concept of object to an existent low-level attention system of the humanoid robot iCub. The objects are defined as clusters of SIFT visual features. When the robot first encounters an unknown object, found to be within a certain (...

A Multi Layer Display (MLD) is a novel device which allows content to be shown on different depth planes. Earlier research indicates that stereoscopic depth information can be beneficial in visual search tasks. This has not yet been explored for this ...

There is deviation between perceived depth andtheoretical depth of virtual object in stereoscopicvirtual environment. This paper analyzes its possiblecauses with optical geometry. In addition, a correctingmethod performed by setting synthetic ...

3d shape and scene layout are often misperceived when viewing stereoscopic displays. For example, viewing from the wrong distance alters an object's perceived size and shape. It is crucial to understand the causes of such misperceptions so one can ...

As the use of virtual and augmented reality applications becomes more common, the need to fully understand how observers perceive spatial relationships grows more critical. One of the key requirements in engineering a practical virtual or augmented ...

Motivation: The purpose of this research is to understand how perceptual depth and information layering techniques can be used to improve the design of computer interfaces for safety critical environments in which failure or delays in observing changes ...

In stereo vision, the measurement of depth perception remains an enigmatic question. On the basis of geometric optics, numerous hypothesis and mathematical formulations have been proposed for explaining the mechanism of depth perception responsible of ...

Three-dimensional sound's effectiveness in virtual reality (VR) environments has been widely studied. However, due to the big differences between VR and augmented reality (AR) systems in registration, calibration, perceptual difference of immersiveness, ...

We present an experiment that compares volumetric displays to existing 3D display techniques in three tasks that require users to perceive depth in 3D scenes. Because they generate imagery in true 3D space, volumetric displays allow viewers to use their ...

In this paper, we introduce a new method for depth perception from a 2D natural scene using scale variation of patterns. As the surface from a 2D scene gets farther away from us, the texture appears finer and smoother. Texture gradient is one of the ...

We hypothesize that one of the reasons for the depth perception problem is the difference between the result for the viewing frustum of virtual world and the scene of the real world. To verify our hypothesis, we experiment simple locating tasks whose ...

There's a big difference between how we look at television, books, and most movies and how we see the rest of the world. Because most of the imagery we look at for work or entertainment is monoscopic, we only see half of what our brains are wired and ...

Using an immersive VR system (the “CAVE”), we investigated the sensitivity and threshold of depth order judgment in the central visual field by subjects placed in a visual environment that simulated optical flow, producing vection in a wide-area visual ...

Fish tank VR systems provide head coupled perspective projected stereo images on a display device of limited dimensions that resides at a fixed location. Therefore, fish tank VR systems provide only a limited virtual workspace. As a result, such systems ...
