For example, compositing is used extensively when combining computer rendered image elements with live footage.

For example, given two image elements A and B, the most common compositing operation is to combine the images such that A appears in the foreground and B appears in the background.

We receive, therefore, in no single intercepting plane behind the system, as, for example, a focusing screen, an image of the object point ; on the other hand, in each of two planes lines O ' and O " are separately formed ( in neighboring planes ellipses are formed ), and in a plane between O ' and O " a circle of least confusion.

The image on the right of a Necker cube is an example of a bistable percept, that is, the cube can be interpreted as being oriented in two different directions.

For example, when an ordinary RGB digital image is compressed via the JPEG standard, the RGB colorspace is first converted ( by a rotation matrix ) to a YCbCr colorspace, because the three components in that space have less correlation redundancy and because the chrominance components can then be subsampled by a factor of 2 or 4 to further compress the image.

For example, the bytes of a plain text file (< tt >. txt </ tt > in Windows ) are associated with either ASCII or UTF-8 characters, while the bytes of image, video, and audio files are interpreted otherwise.

For trajectories other than circular motion, for example, the more general trajectory envisioned in the image above, the instantaneous center of rotation and radius of curvature of the trajectory are related only indirectly to the coordinate system defined by u < sub > ρ </ sub > and u < sub > θ </ sub > and to the length | r ( t )|

For example, text in Microsoft Word will be rendered on the screen with ClearType enhancement, but text placed in a bitmapped image in a program such as Adobe Photoshop will not be modified.

For example, an image may have areas of colour that do not change over several pixels ; instead of coding " red pixel, red pixel, ..." the data may be encoded as " 279 red pixels ".

For example, during the 1980s, character ' Ron Headrest ' served as a doppelgänger for Ronald Reagan and was depicted as a computer-generated artificial-intelligence, an image based on the television character Max Headroom.

With some implementations, image resolution may be less directly limited by bandwidth ; for example in DVB-T, broadcasters can choose from several different modulation schemes, giving them the option to reduce the transmission bitrate and make reception easier for more distant or mobile viewers.

Such systems are useful for modeling, for example, image processing.

) Thus, for example, a 2x6 rectangle and a 3x4 rectangle are equal but not congruent, and the letter R is congruent to its mirror image.

It describes mental processes as computational operations, so that, for example, a fear response is described as arising from a neurological computation that inputs the perceptional data, e. g. a visual image of a spider, and outputs the appropriate reaction, e. g. fear of possibly dangerous animals.

For example, rugby union is both dangerous and adrenaline-inducing but is not considered an extreme sport due to its traditional image, and because it does not involve high speed or an intention to perform stunts ( the aesthetic criteria mentioned above ) and also it does not have changing environmental variables for the athletes.

For example, JPEG compression uses a variant of the Fourier transformation ( discrete cosine transform ) of small square pieces of a digital image.

An image of NGC 4676 ( also called the Mice Galaxies ) is an example of a present merger.

An example of a GIF image saved with a ' web-safe ' palette and dithered using the Floyd – Steinberg dithering | Floyd – Steinberg method.

The trivial example of a large image of solid color demonstrates the variable-length LZW compression used in GIF files.

The house featured in the image of Kings Head St to the left, is unique in the town and is an example of a sailmaker's house, thought to have been built circa 1600. Notable public buildings, all later, include the parish church of St. Nicholas ( 1821 ) in a restrained Gothic style, with many original furnishings including a ( somewhat altered ) organ of the same date in the west end gallery, and the Guildhall of 1769, the only Grade I listed building in Harwich.

Eliphas Levi's image of " Baphomet " serves as an example of the transformation of the Devil into a benevolent fertility deity and provided the prototype for Murray's horned god.

The non-Christian prototype of the Good Shepherd image, for example, was the Kriophoros, the Ram-Bearer, which originally represented Hermes, the shepherd of souls.

For example, a keyframe may be output once for each 10 seconds of video, even though the video image does not change enough visually to warrant the automatic creation of the keyframe.

Occasionally, an image is deliberately windowboxed for stylistic effect ; for example, the documentary-style sequence of the film Rent suggest an older-format camera representing the 4: 3 aspect ratio, and the opening sequence of the Oliver Stone film JFK features pillar boxing to represent the 1960s era 4: 3 television footage.

As with the acetic acid reactions, both definitions work for the first example, where water is the solvent and hydronium ion is formed.

Typically, young children will make an ASL sign in the correct location and use the correct hand motion, but may be able only to approximate the hand shape, for example, using one finger instead of three in signing water.

For example, if the water is 25 ft ( 8 m ) deep, and the anchor roller is 3 ft ( 1 m ) above the water, the scope is the ratio between the amount of cable let out and 28 ft ( 9 m ).

One example is a simple paste made by cooking flour in water.

A common example used in undergraduate education is the determination of the amount of water in a hydrate by heating the sample to remove the water such that the difference in weight is due to the loss of water.

* Magnesium hydroxide is an example of an atypical alkali since it has low solubility in water ( although the dissolved portion is considered a strong base due to complete dissociation of its ions ).

This chart shows that not all fish, shellfish, or the insects that they eat can tolerate the same amount of acid ; for example, frogs can tolerate water that is more acidic ( i. e., has a lower pH ) than trout.

Although it has been known for a while that the Black Sea and the Sea of Marmara flow into each other in an example of a density flow, findings of a study by the University of Leeds in August 2010 reveal that there is in fact an underwater channel of high density water flowing across the floor of the Bosphorus ( caused by the difference in density of the two seas ), which would be the sixth largest river on Earth if it were to be on land.

For example, Dublin has hard water well suited to making stout, such as Guinness ; while Pilsen has soft water well suited to making pale lager, such as Pilsner Urquell.

For example, during the menstrual cycle, the breasts are enlarged by premenstrual water retention ; during pregnancy the breasts become enlarged and denser ( firmer ) because of the prolactin-caused organ hypertrophy, which begins the production of breast milk, increases the size of the nipples, and darkens the skin color of the nipple-areola complex ; these changes continue during the lactation and the breastfeeding periods.

The potential energy is useful, for example, in understanding the concavity of the water surface in a rotating bucket.

For example, water is a compound containing hydrogen and oxygen in the ratio of two to one, with the oxygen atom between the two hydrogen atoms, and an angle of 104. 5 ° between them.

For example, in the case of acetic acid dissolved in water and forming acetate and hydronium ions,

For example, Lowell, Massachusetts, considered to be " The Cradle of the American Industrial Revolution ," has of canals, built from around 1790 to 1850, that provided water power and a means of transportation for the city.

For example, the formula for heavy water may be written D < sub > 2 </ sub > O instead of < sup > 2 </ sup > H < sub > 2 </ sub > O.

As an example of this process, in 2008 Danish researchers first revealed the sequence of events when oxygen and hydrogen combine on the surface of titanium dioxide ( TiO < sub > 2 </ sub >, or titania ) to produce water.

For example, when liquid water starts freezing, the phase change begins with small ice crystals that grow until they fuse, forming a polycrystalline structure.

For example, water ice is ordinarily found in the hexagonal form Ice I < sub > h </ sub >, but can also exist as the cubic Ice I < sub > c </ sub >, the rhombohedral ice II, and many other forms.

For example, water can also form amorphous ice, while SiO < sub > 2 </ sub > can form both fused silica ( an amorphous glass ) and quartz ( a crystal ).

Another example can be found in the 1962 short story Epilogue by Poul Anderson, in which self-replicating factory barges were proposed that used minerals extracted from ocean water as raw materials.

For example, simple hydrogen gas combined with simple oxygen gas can produce a more complex substance, such as water.
