Markus Rupp LVA 389.141 Fachvertiefung Telekommunikation (LVA: 389.137 Image and Video Compression) Last change: Jan 20, 2020 Outline • Binocluar Vision • Stereo Images: From first approaches to standardisation • 3D TV Univ.-Prof. Dr.-Ing. Markus Rupp 2 So far we did only this… This is an eye-pad not an IPad Binocular vision • Binocular vision is vision in which both eyes are used together. The word binocular comes from two Latin roots, bini for double, and oculus for eye.[1] Having two eyes confers at least four advantages over having one. First, it gives a creature a spare eye in case one is damaged. Second, it gives a wider field of view. For example, humans have a maximum horizontal field of view of approximately 200 degrees with two eyes, approximately 120 degrees of which makes up the binocular field of view (seen by both eyes) flanked by two uniocular fields (seen by only one eye) of approximately 40 degrees. [2] Third, it gives binocular summation in which the ability to detect faint objects is enhanced.[3] Fourth it can give stereopsis in which parallax provided by the two eyes' different positions on the head give precise depth perception.[4] Such binocular vision is usually accompanied by singleness of vision or binocular fusion, in which a single image is seen despite each eye's having its own image of any object.[4] Binocular vision • Some animals, usually prey animals, have their two eyes positioned on opposite sides of their heads to give the widest possible field of view.

  • Audiovisual Spatial Congruence, and Applications to 3D Sound and Stereoscopic Video
    Audiovisual spatial congruence, and applications to 3D sound and stereoscopic video. C´edricR. Andr´e Department of Electrical Engineering and Computer Science Faculty of Applied Sciences University of Li`ege,Belgium Thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy (PhD) in Engineering Sciences December 2013 This page intentionally left blank. ©University of Li`ege,Belgium This page intentionally left blank. Abstract While 3D cinema is becoming increasingly established, little effort has fo- cused on the general problem of producing a 3D sound scene spatially coher- ent with the visual content of a stereoscopic-3D (s-3D) movie. The percep- tual relevance of such spatial audiovisual coherence is of significant interest. In this thesis, we investigate the possibility of adding spatially accurate sound rendering to regular s-3D cinema. Our goal is to provide a perceptually matched sound source at the position of every object producing sound in the visual scene. We examine and contribute to the understanding of the usefulness and the feasibility of this combination. By usefulness, we mean that the technology should positively contribute to the experience, and in particular to the storytelling. In order to carry out experiments proving the usefulness, it is necessary to have an appropriate s-3D movie and its corresponding 3D audio soundtrack. We first present the procedure followed to obtain this joint 3D video and audio content from an existing animated s-3D movie, problems encountered, and some of the solutions employed. Second, as s-3D cinema aims at providing the spectator with a strong impression of being part of the movie (sense of presence), we investigate the impact of the spatial rendering quality of the soundtrack on the reported sense of presence.

This thesis contains no material which has been accepted for the award of any other degree or diploma in any university. Shuqi Ng March 2017 ABSTRACT With the implementation of the initiatives in reducing emissions from deforestation and forest degradation (REDD), the accurate determination of the spatio-temporal variation of carbon stocks is crucial. Woody vegetation is one of the more noteworthy carbon storage pools. However, ever-changing forest inventory makes it difficult for countries to accurately measure woody biomass and by extension, predict carbon stocks. Although the most accurate mensuration of biomass is to harvest a tree, the method is destructive and obstructs the REDD initiative. Non- destructive methods use dendrometric measurements that have been obtained from non-contact, remote sensing technologies to estimate biomass derived from allometric models. The commodity stereo-camera is an alternate consideration to remote sensing technologies currently used such as terrestrial laser scanning (TLS), which requires specialized equipment and some expertise in using the equipment. Improving technologies and software has enabled the photogrammetric measurements of objects to be reasonably accurate comparative to TLS. As a more mobile and cost-effective equipment, it also addresses some of the issues in using laser technology. In photogrammetric measurement, the application of spatial scale to the model is critical for accurate distance and volume estimates (Miller (2015)).

    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.

  • Digital Images and Video
    CHAPTER 2 Digital Images and Video Advances in ultra-high-definition and 3D-video technologies as well as high-speed Internet and mobile computing have led to the introduction of new video services. Digital images and video refer to 2D or 3D still and moving (time-varying) visual information, respectively. A still image is a 2D/3D spatial distribution of intensity that is constant with respect to time. A video is a 3D/4D spatio-temporal inten- sity pattern, i.e., a spatial-intensity pattern that varies with time. Another term commonly used for video is image sequence, since a video is represented by a time sequence of still images (pictures). The spatio-temporal intensity pattern of this time sequence of images is ordered into a 1D analog or digital video signal as a function of time only according to a progressive or interlaced scanning convention. We begin with a short introduction to human visual perception and color models in Section 2.1. Next, we present 2D digital video repre-sentations and a brief sum- mary of current standards in Section 2.2. We introduce 3D digital video display, representations, and standards in Section 2.3. Section 2.4 provides an overview of popular digital video applications, including digital TV, digital cinema, and video streaming. Finally, Section 2.5 discusses factors afecting video quality and quanti- tative and subjective video-quality assessment. 53 Tekalp_book_COLOR.indb 53 5/21/15 7:47 PM 54 Chapter 2.

Haubeck a, T. Prinz b a Institute of Geography, Westfalian Wilhelms-University Münster, Germany – [email protected] b Institute for Geoinformatics, Westfalian Wilhelms-University Münster, Germany – [email protected] KEY WORDS: Archaeology, Application, DEM/DTM, Orthoimage, Close Range, UAV, Stereoscopic ABSTRACT: The use of Unmanned Aerial Vehicles (UAVs) for surveying archaeological sites is becoming more and more common due to their advantages in rapidity of data acquisition, cost-efficiency and flexibility. One possible usage is the documentation and visualization of historic geo-structures and -objects using UAV-attached digital small frame cameras. These monoscopic cameras offer the possibility to obtain close-range aerial photographs, but – under the condition that an accurate nadir-waypoint flight is not possible due to choppy or windy weather conditions – at the same time implicate the problem that two single aerial images not always meet the required overlap to use them for 3D photogrammetric purposes. In this paper, we present an attempt to replace the monoscopic camera with a calibrated low-cost stereo camera that takes two pictures from a slightly different angle at the same time. Our results show that such a geometrically predefined stereo image pair can be used for photogrammetric purposes e.g. the creation of digital terrain models (DTMs) and orthophotos or the 3D extraction of single geo-objects.
