Image

An image (from Latin: imago) is an artifact that depicts visual perception, for example a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.

Characteristics

Images may be two-dimensional, such as a photograph, screen display, and as well as a three-dimensional, such as a statue or hologram. They may be captured by optical devices – such as cameras, mirrors, lenses, telescopes, microscopes, etc. and natural objects and phenomena, such as the human eye or water.

The word image is also used in the broader sense of any two-dimensional figure such as a map, a graph, a pie chart, or a painting. In this wider sense, images can also be rendered manually, such as by drawing, the art of painting, carving, rendered automatically by printing or computer graphics technology, or developed by a combination of methods, especially in a pseudo-photograph.

A volatile image is one that exists only for a short period of time. This may be a reflection of an object by a mirror, a projection of a camera obscura, or a scene displayed on a cathode ray tube. A fixed image, also called a hard copy, is one that has been recorded on a material object, such as paper or textile by photography or any other digital process.

Image (Angel novel)

Image is an original novel based on the U.S. television series Angel.

Plot summary

Cordelia Chase has a vision of a child being attacked by a squidlike demon. Meanwhile, Gunn is trying to rescue a young artist; the artist's studio is being attacked by vampires. Cordelia goes to investigate the mansion from her vision. She soon finds herself surrounded by baby products, portraits, and chased by a tentacled monster.

When Angel arrives on the scene, he is surprised to discover that he recognizes some of the portraits. He holds distant memories of him and Darla spending a night with storytellers and artists. Angel reveals that he and Darla were present at the party where Mary Shelley was inspired to write Frankenstein; indeed, they witnessed the event that gave Mary the initial idea.

An old evil is trying to use a painting to preserve the life of its body, which, in the terms of the story, inspired the novel The Picture of Dorian Gray. In their efforts to save a child the villain is focused on, Team Angel will learn not to judge everything by its image.

Image (category theory)

Given a category C and a morphism in C, the image of f is a monomorphism satisfying the following universal property:

There exists a morphism such that .

For any object Z with a morphism and a monomorphism such that , there exists a unique morphism such that .

Remarks:

The image of f is often denoted by im f or Im(f).

One can show that a morphism f is epic if and only if f = im f.

Examples

In the category of sets the image of a morphism is the inclusion from the ordinary image to . In many concrete categories such as groups, abelian groups and (left- or right) modules, the image of a morphism is the image of the correspondent morphism in the category of sets.

In any normal category with a zero object and kernels and cokernels for every morphism, the image of a morphism can be expressed as follows:

Offshore (novel)

Offshore (1979) is a novel by Penelope Fitzgerald. It won the Booker Prize for that year. It recalls her time spent on boats on the Thames in Battersea. The novel explores the liminality of people who do not belong to the land or the sea, but are somewhere in between. The epigraph, "che mena il vento, e che batte la pioggia, e che s'incontran con si aspre lingue" ("whom the wind drives, or whom the rain beats, or those who clash with such bitter tongues") comes from Canto XI of Dante's Inferno.

Offshore (hydrocarbons)

"Offshore", when used relative to hydrocarbons, refers to an oil, natural gas or condensate field that is under the sea, or to activities or operations carried out in relation to such a field. There are various types of platform used in the development of offshore oil and gas fields, and subsea facilities.

Offshore exploration is performed with floating drilling units.
