{In common usage, an image (from Latinimago) or picture is an artefact that reproduces the likeness of some subject—usually a physical object or a person.
Images may be two-dimensional (e.g. a photograph) or three dimensional (e.g. 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-dimensional figure or illustration, e.g. a map, a graph, a pie chart, an abstract painting, etc. In this wider sense, images can also be produced manually (by drawing, painting, carving, etc.), by computer graphics technology, or a combination of the two (see pseudo-photograph).
A volatile image is one that exists only for a short period of time, e.g. the reflection of an object by a mirror, a projection of the sun on a wall by a pinhole camera, or a scene displayed on a cathode ray tube. A fixed image, also called hardcopy, is one that has been recorded on a material object, such as paper or textile.
A mental image exists in someone's mind: something one remembers or imagines. The subject of an image need not be real; it may be an abstract concept, such as a graph or function—or an imaginary entity or being.
In many other scientific and technical contexts, image usually means a two-dimensional signal—a physical phenomenon that can be modeled as a function from a two-dimensional domain (such as the plane or a rectangle) to some set of values, usually real numbers or vectors. This sense covers not only digital images but also analog ones, such as photographs. See image processing.
In computer science the word image can also mean an exact (bit-by-bit) copy of the contents of some device, such as a hard disk, floppy disk, CD-ROM, etc.. In particular,
An executable image is a structured file containing machine instructions and data, which can be loaded into a process's virtual memory and executed. See kernel (computers).
In mathematics, an image is a value or set of values of a function. Specifically, let f be a function from the setX to the set Y. If a is an element of X, then its image under f is the value f(a). If A is a subset of X, then its image under f is f(A) = {f(a) : a∈A}. Finally, the image of f itself is f(X), i.e. the same as the range of f.
Kenyon College is a highly-selective private liberal arts college founded in Gambier, Ohio in 1824, by Episcopal Bishop Philander Chase. It is Ohio's oldest private institute of higher learning. Originally an all-male institution aligned with the Episcopal Church, it became co-educational in 1969.
Kenyon's English department is probably the best known among Kenyon's excellent academic departments. Its distinguished alumni include poet and critic John Crowe Ransom, poet Robert Lowell, and novelist E.L. Doctorow.
The Kenyon Review, a literary magazine, was founded in 1939.
Kenyon's men's and women's swimming teams led by Jim Steen are generally considered the best in NCAA Division III, with the men's team winning 25 consecutive national championships and the women's 20. Jim Steen is the winningest coach in any sport in NCAA history.
Kenyon's sports teams are referred to as the Lords and Ladies, and their colors are purple and white.
