  • Depth Inversion Despite Stereopsis: the Appearance of Random-Dot Stereograms on Surfaces Seen in Reverse Perspective
    Perception, 1979, volume 8, pages 135-142 Depth inversion despite stereopsis: the appearance of random-dot stereograms on surfaces seen in reverse perspective John I Yellott, Jr, Jerry L Kaiwi Cognitive Science Group, School of Social Sciences, University of California at Irvine, Irvine, California 92717, USA Received 20 October 1977, in revised form 18 October 1978 Abstract. Inside-out relief masks of faces can be depth-inverted (i.e. seen in reverse perspective) during close-up binocular viewing. If a random-dot stereogram is projected onto such a mask, stereopsis can be achieved for the stereogram, and its depth planes are correctly seen while the mask itself, including the region covered by the stereogram, is simultaneously perceived as depth- inverted. This demonstration shows that binocular depth inversion cannot be explained by a complete loss of stereoscopic information (e.g. through monocular suppression), or by a process analogous to pseudoscopic viewing whereby retinal disparities are incorporated into perception, but with their signs uniformly reversed. 1 Introduction Reversible perspective is probably most often thought of in connection with ambiguous pictures like the Necker cube (figure la), but it is also well-known that depth reversals can sometimes be experienced with solid objects, and with far more dramatic perceptual consequences. [Gregory (1970) describes these in detail; Helmholtz (1925) reviews references back to 1712, and Hochberg (1972) and Robinson (1972) review the modern literature, which is surprisingly thin.] In this note we use 'depth inversion' to refer specifically to this second kind of reversible perspective, in which real objects (rather than depicted ones) are perceived, from the standpoint of depth, as inside-out, so that their concave surfaces appear convex and vice versa.

Papathomas 1,*, Kazunori Morikawa 2 and Nicholas Wade 3 1 Laboratory of Vision Research, Center for Cognitive Science, and Department of Biomedical Engineering, Rutgers University, Piscataway, NJ 08854, USA 2 School of Human Sciences, Osaka University, Suita, Osaka 565-0871 Japan; [email protected] 3 Department of Psychology, University of Dundee, Nethergate, Dundee DD1 4HN, UK; [email protected] * Correspondence: [email protected]; Tel.: +1-848-445-6533 Received: 23 March 2019; Accepted: 5 May 2019; Published: 8 May 2019 Abstract: A brief tribute to Bela Julesz (1928–2003) is made in words and images. In addition to a conventional stereophotographic portrait, his major contributions to vision research are commemorated by two ‘perceptual portraits’, which try to capture the spirit of his main accomplishments in stereopsis and the perception of texture. Keywords: depth perception; stereopsis; texture; perceptual portrait; random-dot stereograms Binocular vision has been a topic of enquiry for at least two millennia but linking retinal disparity to depth perception is much more recent. Almost two centuries ago, the invention of the stereoscope by Wheatstone [1] revolutionized the experimental investigation of binocular vision. Separating the perception of depth from object recognition (with random-dot stereograms [2]) heralded a second revolution. It is then fitting that a scientist who contributed so much to our understanding of stereoscopic vision should be presented stereoscopically, as in Figure1. Most significantly, Bela Julesz is also represented in two ‘perceptual portraits’. Their aim is to combine his portrait with graphical elements that reflect the contributions that he made to the study of mind and behavior—after the manner of those displayed in Wade’s book [3].

    A Stereo/Photo Glossary Page 1 of 34 A STEREO/PHOTO GLOSSARY (Second edition, version 93.5/97.4a) by: Craig Daniels and Dr. Dale E. Hammerschmidt This short work is intended for anyone interested in stereoscopic pursuits, but particularly for those who are trying to create stereoscopic images. We hope that the words and phrases to be found here will become useful tools rather than obstacles in your approach to "3-D" imaging. We stress that this is a compendium of terms that we have found useful, confusing and/or interesting; while we have tried to make it accurate, we do not represent that it is complete or of great scholarly depth. Some entries are long, because we found the subject interesting or we knew a lot about it; some are short for the obvious other reasons! We have tried to keep the tone conversational, rather than strive for uniform and rigid style; we've not felt ourselves above an occasional wise-crack. Additions, corrections and improvements are always welcome --- we see ourselves as editors rather than authors. (Glossary is available via diskette or e-mail.) * ANSI: American National Standards Institute. See next entry. * ASA: (1) American Standards Association. Although the expression "ASA" is still applied to U.S. film speeds, the "American Standards Association" changed its name to the "American National Standards Institute" in 1969. Their standards are referenced by ANSI numbers such as "PH3.11-1953" (which describes the 5p format used in cameras like the Stereo Realist and the Kodak Stereo 35).

Fulton Vision Concepts [email protected] April 30, 2017 Copyright 2004 James T. Fulton Dynamics of Vision 7- 1 7 Dynamics of Vision 1 The dynamics of the visual process have not been assembled and presented in a cogent manner within the academic vision literature. On the other hand, several authors have presented cogent descriptions applicable to the clinical level. The material assembled by Salmon at Northeastern State University2 in Oklahoma is exemplary (but superficial for the purpose at hand). The dynamics associated with the mechanism of interpreting symbols and character groups, called reading, has not been presented at all. Only the major eye movements related to reading have been studied in significant detail. Even the adaptation characteristic of vision as a function of illumination level has not been presented from a theoretical perspective, and the empirical data has not been analyzed in sufficient detail to provide a coherent understanding of the process. When assembled as a group, the mechanisms and processes associated with forming the chromophores of vision provide a new, interesting and unique perspective on the formation of those chromophores. This Chapter will assemble the pertinent data with respect to a variety of processes where their dynamic aspects are crucial to the visual function. 7.1 Characteristics & Dynamics of Retinoids in the body The following material is based on extensive empirical investigations that were largely lacking with regard to any contiguous theory of what the goals of the mechanisms involved were from the perspective of the visual modality.

In fruit flies, as in mammals, spermatogenesis takes place within the context of the testes. The cellular transformations that occur in mammals during spermatogenesis are closely mimicking in fruit flies, thus making flies an excellent model for studying spermatogenesis. Dr. Angela Klaus of the Department of Biological Sciences at Seton Hall University will present results of current work looking at spermatogenesis in the fruit fly Drosophila pseudoobscura using confocal microscopy. She will also present some preliminary AFM analyses of sperm morphology in the white-tailed deer. Doors will be open at Noon. Refreshments will be available.
