Free-viewpoint Television
Free viewpoint television (FTV) is a system for viewing natural video, allowing the user to interactively control the viewpoint and generate new views of a dynamic scene from any 3D position. The equivalent system for computer-simulated video is known as virtual reality. With FTV, the focus of attention can be controlled by the viewers rather than a director, meaning that each viewer may be observing a unique viewpoint. It remains to be seen how FTV will affect television watching as a group activity. History Systems for rendering arbitrary views of natural scenes have been well known in the computer vision community for a long time but only in recent years has the speed and quality reached levels that are suitable for serious consideration as an end-user system. Professor Masayuki Tanimoto from Nagoya University (Japan) has done much to promote the use of the term "free viewpoint television" and has published many papers on the ray space representation, although other technique ...

View Synthesis
View synthesis aims to create new views of a specific subject starting from a number of pictures taken from given point of views. Currently a study branch of Computer Science Research, Vision Research and Artificial Intelligence fields are involved in the definition of suitable approaches to the problem. See Computer Vision Example problem 1: Is to take a number of images of a specific subject, taken from a specific point with a specific camera orientation and setting, and then use that data to build a synthetic image that looks as if it was taken from a virtual camera that is placed at a different point and with the same settings. Example problem 2: Two people interact through their computers, using a webcam. Try to render corrected images, as if taken from a virtual webcam positioned behind the application window. This would solve the long-standing Eye contact problem which is experienced in this environment. A double illusion is perceived by the users: each of them looks at ea ...

Rendering (computer Graphics)
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a ''scene file'' containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene. The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output. Rendering is one of the major sub-topics of 3D computer graphics, and in practice it is always connected to the others. It is the last major step in the gr ...

Applications Of Computer Vision
Computer vision is an interdisciplinary scientific field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to understand and automate tasks that the human visual system can do. Computer vision tasks include methods for acquiring, processing, analyzing and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e.g. in the forms of decisions. Understanding in this context means the transformation of visual images (the input of the retina) into descriptions of the world that make sense to thought processes and can elicit appropriate action. This image understanding can be seen as the disentangling of symbolic information from image data using models constructed with the aid of geometry, physics, statistics, and learning theory. The scientific discipline of computer vision is concerned with the theory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Technology
Large-screen television technology (colloquially big-screen TV) developed rapidly in the late 1990s and 2000s. Prior to the development of thin-screen technologies, rear-projection television was standard for larger displays, and jumbotron, a non-projection video display technology, was used at stadiums and concerts. Various thin-screen technologies are being developed, but only liquid crystal display (LCD), plasma display (PDP) and Digital Light Processing (DLP) have been publicly released. Recent technologies like organic light-emitting diode (OLED) as well as not-yet-released technologies like surface-conduction electron-emitter display (SED) or field emission display (FED) are in development to replace earlier flat-screen technologies in picture quality. Large-screen technologies have almost completely displaced cathode-ray tubes (CRT) in television sales due to the necessary bulkiness of cathode-ray tubes. The diagonal screen size of a CRT television is limited to abou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Year Of Introduction Missing
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mean ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Vision
An area of computer vision is active vision, sometimes also called active computer vision. An active vision system is one that can manipulate the viewpoint of the camera(s) in order to investigate the environment and get better information from it. Background The interest in active camera system started as early as two decades ago. Beginning in the late 1980s, Aloimonos et al. introduced the first general framework for active vision in order to improve the perceptual quality of tracking results. Active vision is particularly important to cope with problems like occlusions, limited field of view and limited resolution of the camera. Other advantages can be reducing the motion blur of a moving object and enhancing depth perception of an object by focusing two cameras on the same object or moving the cameras. Active control of the camera view point also helps in focusing computational resources on the relevant element of the scene. In this selective aspect, active vision can be see ...

Super Bowl XXXV
Super Bowl XXXV was an American football game between the American Football Conference (AFC) champion Baltimore Ravens and the National Football Conference (NFC) champion New York Giants to decide the National Football League (NFL) champion for the 2000 season. The Ravens defeated the Giants by a score of 34–7, tied for the seventh largest Super Bowl margin of victory with Super Bowl XXXVII. The game was played on January 28, 2001, at Raymond James Stadium in Tampa, Florida. The Ravens, who posted a 12–4 regular season record, became the third wild card team to win the Super Bowl and the second in four years. The Giants entered the game seeking to go 3–0 in Super Bowls after also finishing the regular season with a 12–4 record. Baltimore allowed only 152 yards of offense by New York (the third-lowest total ever in a Super Bowl), recorded 4 sacks, and forced five turnovers. All sixteen of the Giants' possessions ended with punts or interceptions, with the exception of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
