Art forgery means creating and especially selling works of art that are falsely attributed to be work of other, usually more famous artists. Art forgery is extremely lucrative, but modern dating and analysis techniques make the identification of a piece of art much simpler. Art forgery - History. Art forgery dates back more than two-thousand years. Roman sculptors produced copies of Greek sculptures. Presumably the contemporary buyers knew that they were not genuine. Before the commercial art market, ...

In common usage, an image (from Latin imago) or picture is an artifact that reproduces the likeness of some subject—usually a physical object or a person. Images may be two dimensional, such as a photograph, or three dimensional such as in a statue. They are typically produced by optical devices—such as a cameras, mirrors, lenses, telescopes, microscopes, etc. and natural objects and phenomena, such as the human eye or water surfaces. The word image' is also used in the broader sense of any two-d ...

Computer vision is the study and application of methods which allow computers to "understand" image content or content of multidimensional data in general. The term "understand" means here that specific information is being extracted from the image data for a specific purpose: either for presenting it to a human operator (e. g., if cancerous cells have been detected in a microscopy image), or for controlling some process (e. g., an industry robot or an autonomous vehicle). The image data that is fed into a computer vision system is of ...

2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models (such as 2D geometric models, text, and digital images) and by techniques specific to them. The word may stand for the branch of computer science that comprises such techniques, or for the models themselves. 2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies, such as typography, cartography, technical drawing, advertising, etc.. In those ...

Color negatives and ordinary color prints fade away to nothing in a relatively short period. This happens even if the negatives and prints are kept in the dark. Because color processing results in a less stable image than traditional black-and-white processing, pictures from the 1920s are more likely to survive into the long term future than those from the last 20 or 30 years. The cause of this is the use of inferior photo paper and ink, and the in ...

Because of the computational load of dealing with images containing millions of pixels, digital image processing was largely of academic interest until the 1970s, when dedicated hardware became available that could process images in real time, for some dedicated problems such as television standards conversion. As general-purpose computers became faster, they started to take over the role of dedicated hardware for all but th ...

Most people are familiar with the digital animations produced to present meteorological data during weather reports on television, though few can distinguish between those models of reality and the satellite photos which are also shown on such programs. TV also offers scientific visualizations when it shows computer drawn and animated reconstructions of road or airplane accidents. Some of the most popular examples of scientific visualizations are computer generated images which show real spacecraft in action, out in the void far beyond Earth ...

Information stored in high dynamic range (HDR) images usually correspond to the physical values of luminance or radiance that can be observed in the real world. This is different to traditional digital images, which represent colors that should appear on a monitor or a paper print. Therefore HDR image formats are often called scene-referred, in contrast to traditional digital images, which are device-referred or output-referred. Furthermore, traditional images are usually encoded for the human visual system (maximizing the visual information ...

The use of SVG on the web is in its infancy. There is a great deal of inertia from the long-time use of pure raster formats and other formats like Macromedia Flash or Java applets, but also browser support is patchy, with most browsers requiring a plugin. Web sites which serve SVG images typically also provide the images in a raster format, either automatically by HTTP content negotiation or allowing the user to directly choose the file. Alternative images are usually automatically rasterised using a library such as ImageMagick, which provides a quick but incomplete implementatio ...

Film recorders are used in digital printing to generate master negatives for offset and other bulk printing processes. They are also used to produce the master copies of movies that use computer animation or other special effects based on digital image processing. For preview, archiving, and small-volume reproduction, film recorders have been rendered obsolete by modern printers that produce photographic-quality hardcopies directly on plain paper. Film recorders were also commonly used to produce slides for slide projectors; but this need is now largely met by video projectors that project images ...

Since the early nineties, a growing sector of global print production has been Digital, as distinguished from Litho print. Digital Print is used by those requiring the following: Short to medium run colour and mono work Fast turnaround (Digital Print requires less drying time than traditional ink) Personalisation (As the image is reproduced each time, variations can be easily introduced) Print on Demand (ie. with an automated ordering system) The advantage over Litho for short run work is that no plates are n ...

The field of computer vision can be characterized as immature and diverse. Even though earlier work exists, it was not until the late 1970's that a more focused study of the field started when computers could manage the processing of large data sets such as images. However, these studies usually originated from various other fields, and consequently there is no standard formulation of the "computer vision problem". Also, and to an even larger extent, there is no standard formulation of how computer vision problems should be solved. Instead, ...

2D graphics models may combine geometric models (also called vector graphics), digital images (also called raster graphics), text to be typeset (defined by content, font style and size, color, position, and orientation), mathematical functions and equations, and more. These components can be modified and manipulated by two-dimensional geometric transformations such as translation, rotation, scaling. In object oriented graphics, the image is described indirectly by an object endowed with a self-rendering method—a procedure which assi ...

The most obvious forgeries are revealed because they are just clumsy copies of previous art. Forger may try to create a "new" work by combining elements of more than one work. They may omit details typical to the artist they are trying to imitate or add anachronisms. They may also try to claim that a slightly different copy is a previous version of the more famous work. However, if the forger is skilled enough to create something new that is reminiscent of the style of a specif ...
