Recent work on the architecture of attention shows that it has simultaneous access to multiple selections, and luckily so, because other studies show that it is impossible to scrutinise the details within a single selection. As a result, the integration of elements, the derivation of their relations, and the actions they are engaged in is only possible by comparing information across multiple selections. The product of this cross-selection is a language-like description of the visual event that is then exported to other modules in the brain. A basic distinction immediately arises between objects (`nouns') that can be selected rapidly with a single operation, and actions (`verbs') that always require multiple selections. Results from parietal patients demonstrate a candidate case of syntax for motion and transient events.

Better recognition accuracy can be achieved by the determination of the positions of salient image locations. Most of the facial-feature-selection algorithms in the literature work with two assumptions: one, that the importance of each feature is independent of the other features; and, two, that the kernels should be located at fiducial points. Under these assumptions, one can only get a suboptimal solution. Here, we present a methodology that tries to overcome this problem by relaxing the two assumptions by using a formalism of subset selection problem. In addition to the topographical information, resolution and orientation are also the two important parameters of a feature extractor, since face contains features having different orientation and resolution. Therefore, it is natural to design a feature extractor which takes into account these characteristics of faces. Among several alternatives, 2-D Gabor wavelets are very suitable for this task. The selection of resolution and orientation parameters at specific face locations is also carried out by a supervised sequential floating subset search. This step concludes our two-level feature selection methodology, in which the first step extracts topographical importance, and the second step extracts frequency and orientation infor- mation. Experiments on the FERET data set are presented, and the validity of the approach is discussed. ^ Non-classical receptive field inhibition and contour detection N Petkov, M A Westenberg, C Grigorescu (Institute of Mathematics and Computing Science, University of Groningen, PO Box 800, NL 9700 AV Groningen, The Netherlands; e-mail: [email protected]; website: www.cs.rug.nl/petkov) Various visual effects show that the perception of an edge or a line can be influenced by other such stimuli in the surroundings.

  • Virtual Reality and Visual Perception by Jared Bendis
    Virtual Reality and Visual Perception by Jared Bendis Introduction Goldstein (2002) defines perception as a “conscious sensory experience” (p. 6) and as scientists investigate how the human perceptual system works they also find themselves investigating how the human perceptual system doesn’t work and how that system can be fooled, exploited, and even circumvented. The pioneers in the ability to control the human perceptual system have been in the field of Virtual Realty. In Simulated and Virtual Realities – Elements of Perception, Carr (1995) defines Virtual Reality as “…the stimulation of human perceptual experience to create an impression of something which is not really there” (p. 5). Heilig (2001) refers to this form of “realism” as “experience” and in his 1955 article about “The Cinema of the Future” where he addresses the need to look carefully at perception and breaks down the precedence of perceptual attention as: Sight 70% Hearing 20% Smell 5% Touch 4% Taste 1% (p. 247) Not surprisingly sight is considered the most important of the senses as Leonardo da Vinci observed: “They eye deludes itself less than any of the other senses, because it sees by none other than the straight lines which compose a pyramid, the base of which is the object, and the lines conduct the object to the eye… But the ear is strongly subject to delusions about the location and distance of its objects because the images [of sound] do not reach it in straight lines, like those of the eye, but by tortuous and reflexive lines. … The sense of smells is even less able to locate the source of an odour.

    ChromoStereoscopic Rendering for Trichromatic Displays Le¨ıla Schemali1;2 Elmar Eisemann3 1Telecom ParisTech CNRS LTCI 2XtremViz 3Delft University of Technology Figure 1: ChromaDepth R glasses act like a prism that disperses incoming light and induces a differing depth perception for different light wavelengths. As most displays are limited to mixing three primaries (RGB), the depth effect can be significantly reduced, when using the usual mapping of depth to hue. Our red to white to blue mapping and shading cues achieve a significant improvement. Abstract The chromostereopsis phenomenom leads to a differing depth per- ception of different color hues, e.g., red is perceived slightly in front of blue. In chromostereoscopic rendering 2D images are produced that encode depth in color. While the natural chromostereopsis of our human visual system is rather low, it can be enhanced via ChromaDepth R glasses, which induce chromatic aberrations in one Figure 2: Chromostereopsis can be due to: (a) longitunal chro- eye by refracting light of different wavelengths differently, hereby matic aberration, focus of blue shifts forward with respect to red, offsetting the projected position slightly in one eye. Although, it or (b) transverse chromatic aberration, blue shifts further toward might seem natural to map depth linearly to hue, which was also the the nasal part of the retina than red. (c) Shift in position leads to a basis of previous solutions, we demonstrate that such a mapping re- depth impression. duces the stereoscopic effect when using standard trichromatic dis- plays or printing systems.

  • A Novel Walk-Through 3D Display
    A Novel Walk-through 3D Display Stephen DiVerdia, Ismo Rakkolainena & b, Tobias Höllerera, Alex Olwala & c a University of California at Santa Barbara, Santa Barbara, CA 93106, USA b FogScreen Inc., Tekniikantie 12, 02150 Espoo, Finland c Kungliga Tekniska Högskolan, 100 44 Stockholm, Sweden ABSTRACT We present a novel walk-through 3D display based on the patented FogScreen, an “immaterial” indoor 2D projection screen, which enables high-quality projected images in free space. We extend the basic 2D FogScreen setup in three ma- jor ways. First, we use head tracking to provide correct perspective rendering for a single user. Second, we add support for multiple types of stereoscopic imagery. Third, we present the front and back views of the graphics content on the two sides of the FogScreen, so that the viewer can cross the screen to see the content from the back. The result is a wall- sized, immaterial display that creates an engaging 3D visual. Keywords: Fog screen, display technology, walk-through, two-sided, 3D, stereoscopic, volumetric, tracking 1. INTRODUCTION Stereoscopic images have captivated a wide scientific, media and public interest for well over 100 years. The principle of stereoscopic images was invented by Wheatstone in 1838 [1]. The general public has been excited about 3D imagery since the 19th century – 3D movies and View-Master images in the 1950's, holograms in the 1960's, and 3D computer graphics and virtual reality today. Science fiction movies and books have also featured many 3D displays, including the popular Star Wars and Star Trek series. In addition to entertainment opportunities, 3D displays also have numerous ap- plications in scientific visualization, medical imaging, and telepresence.

Kanizsa triangles were induced by black pacman disks consisting of red sectors with curved sides. Viewing our stimuli monocularly produced two-dimensional illusory contours and surfaces as well as neon spreading in each ®gure. Triangles appeared concave or convex under stereoscopical viewing. Neon colour spreading was induced within illusory ®gures bending in three-dimensional space, suggesting that neural contour completion and surface ®lling-in interact across depth. Surpris- ingly, neon spreading was induced above the intervening surface even when the inducers were below the surface. Neon colour and illusory con®guration were preserved behind the intervening surface only when it appeared transparent. q 2000 Elsevier Science Ireland Ltd. All rights reserved.

    There are 500 Stories at 3D-Con: This is One of Them I would like to welcome you to 3D-Con, a combined convention for the ISU and NSA. This is my second convention that I have been chairman for and fourth Southern California one that I have attended. Incidentally the first convention I chaired was the first one that used the moniker 3D-Con as suggested by Eric Kurland. This event has been harder to plan due to the absence of two friends who were movers and shakers from the last convention, David Washburn and Ray Zone. Both passed before their time soon after the last convention. I thought about both often when planning for this convention. The old police procedural movie the Naked City starts with the quote “There are eight million stories in the naked city; this has been one of them.” The same can be said of our interest in 3D. Everyone usually has an interesting and per- sonal reason that they migrated into this unusual hobby. In Figure 1 My Dad and his sister on a keystone view 1932. a talk I did at the last convention I mentioned how I got inter- ested in 3D. I was visiting the Getty Museum in southern Cali- fornia where they had a sequential viewer with 3D Civil War stereoviews, which I found fascinating. My wife then bought me some cards and a Holmes viewer for my birthday. When my family learned that I had a stereo viewer they sent me the only surviving photographs from my fa- ther’s childhood which happened to be stereoviews tak- en in 1932 in Norwalk, Ohio by the Keystone View Com- pany.

    3D television - Wikipedia https://en.wikipedia.org/wiki/3D_television From Wikipedia, the free encyclopedia 3D television (3DTV) is television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. Most modern 3D television sets use an active shutter 3D system or a polarized 3D system, and some are autostereoscopic without the need of glasses. According to DisplaySearch, 3D televisions shipments totaled 41.45 million units in 2012, compared with 24.14 in 2011 and 2.26 in 2010.[1] As of late 2013, the number of 3D TV viewers An example of three-dimensional television. started to decline.[2][3][4][5][6] 1 History 2 Technologies 2.1 Displaying technologies 2.2 Producing technologies 2.3 3D production 3TV sets 3.1 3D-ready TV sets 3.2 Full 3D TV sets 4 Standardization efforts 4.1 DVB 3D-TV standard 5 Broadcasts 5.1 3D Channels 5.2 List of 3D Channels 5.3 3D episodes and shows 5.3.1 1980s 5.3.2 1990s 5.3.3 2000s 5.3.4 2010s 6 World record 7 Health effects 8See also 9 References 10 Further reading The stereoscope was first invented by Sir Charles Wheatstone in 1838.[7][8] It showed that when two pictures 1 z 17 21. 11. 2016 22:13 3D television - Wikipedia https://en.wikipedia.org/wiki/3D_television are viewed stereoscopically, they are combined by the brain to produce 3D depth perception.

  • The Mccollough Effect: Dissociating Retinal from Spatial Coordinates
    Perception & Psychophysics 1993. 54 (4). 515-526 The McCollough effect: Dissociating retinal from spatial coordinates FELICE L. BEDFORD and KAREN S. REINKE University ofArizona, Tucson, Arizona Three experiments were conducted to dissociate the perceived orientation of a stimulus from its orientation on the retina while inducing the McCollough effect. In the first experiment, the typical contingency between color and retinal orientation was eliminated by having subjects tilt their head 90 0 for half of the induction trials while the stimuli remained the same. The only relation remaining was that between color and the perceived or spatial orientation, which led to only a small contingent aftereffect. In contrast, when the spatial contingency was eliminated in the second experiment, the aftereffect was as large as when both contingencies were present. Finally, a third experiment determined that part of the small spatial effect obtained in the first experiment could be traced to hidden higher order retinal contingencies. The study suggested that even under optimal conditions the McCollough effect is not concerned with real-world prop­ erties of objects or events. Implications for several classes of theories are discussed. The McCollough effect (ME) is viewed by some re­ how many pairs of attributes other than color and oriented searchers to be an instance of learning; the most well de­ lines can lead to contingent aftereffects (see Dodwell & veloped explanation in that class has appealed to Pavlov­ Humphrey, 1990; Harris, 1980; Siegel et al. 1992; ian conditioning (e.g., Allan & Siegel, 1986; Murch, 1976; Skowbo, 1984; Stromeyer, 1978)?

  • Introducing the Scintillating Starburst: Illusory Ray Patterns from Spatial Coincidence Detection
    Introducing the scintillating starburst: Illusory ray patterns from spatial coincidence detection 1 2 Michael W Karlovich ​ & Pascal Wallisch ​ ​ 1 Recursia Labs. 2 Department of Psychology, New York University Abstract Here, we introduce a novel class of visual illusion, the “Scintillating Starburst”, which features illusory scintillating rays or beams. We show empirically what combination of factors modulate how an observer experiences this kind of stimulus. We explain how the illusion arises from the interplay of known visual processes, specifically magnocellular and parvocellular dynamics and relate the effects of these ray patterns to other known visual illusions such as illusory contours. Introduction Illusions have played a key role in understanding the principles of perceptual processing (Purkinje, 1825; van Buren & Scholl, 2018), although this notion is not entirely without detractors (Braddick, 2018; Rogers, 2019). One important reason why illusions can be helpful is that they allow us to distinguish the mere sensation of physical object properties from the perceptual experience. This is perhaps clearest in the case of illusory contours. If contours are defined by a sharp change in luminance, it is hard to tell whether the observer “directly” perceives objects in the environment “as they are” or if the percept is constructed in the mind of the observer, because the output of a photometer and perceptual judgments agree (Gibson, 1978; Fodor & Pylyshyn, 1981). Conversely, illusory contours are not defined by changes in luminance, and would be invisible to a photometer, whereas human observers readily perceive them. One example of this is Kanisza’s triangle, which most observers perceive as a bright triangle occluding three black circles - as opposed to the three black pac-man-like shapes are actually defined by luminance (Kanisza, 1955).
