Image resolution

Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.

Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtense. Line pairs are often used instead of lines; a line pair comprises a dark line and an adjacent light line. A line is either a dark line or a light line. A resolution of 10 lines per millimeter means 5 dark lines alternating with 5 light lines, or 5 line pairs per millimeter (5 LP/mm). Photographic lens and film resolution are most often quoted in line pairs per millimeter.

Resolution of digital images

The resolution of digital cameras can be described in many different ways.

High-resolution scheme

High-resolution schemes are used in the numerical solution of partial differential equations where high accuracy is required in the presence of shocks or discontinuities. They have the following properties:

General methods are often not adequate for accurate resolution of steep gradient phenomena; they usually introduce non-physical effects such as smearing of the solution or spurious oscillations. Since publication of Godunov's order barrier theorem, which proved that linear methods cannot provide non-oscillatory solutions higher than first order (Godunov-1954, Godunov-1959), these difficulties have attracted a lot of attention and a number of techniques have been developed that largely overcome these problems. To avoid spurious or non-physical oscillations where shocks are present, schemes that exhibit a Total Variation Diminishing (TVD) characteristic are especially attractive.

Portland, Oregon

Portland (/ˈpɔːrtlənd/) is the largest city in the U.S. state of Oregon and the seat of Multnomah County. It is located in the Willamette Valley region of the Pacific Northwest, at the confluence of the Willamette and Columbia rivers. The city covers 145 square miles (376 km²) and had an estimated population of 619,360 in 2014, making it the 28th most populous city in the United States. Approximately 2,348,247 people live in the Portland metropolitan statistical area (MSA), the 24th most populous MSA in the United States. Its Combined Statistical Area (CSA) ranks 17th with a population of 3,022,178. Roughly 60 percent of Oregon's population resides within the Portland metropolitan area.

Named after the city in Maine, Portland was settled in the 1830s near the end of the Oregon Trail. Its water access provided convenient transportation of goods, and the timber industry was a major force in the city's early economy. At the turn of the 20th century, the city had developed a reputation as one of the most dangerous port cities in the world, a hub for organized crime and racketeering. After the city's economy experienced an industrial boom during World War II, its hard-edged reputation began to dissipate. Beginning in the 1960s, Portland became noted for its growing liberal political values, and the city has earned a reputation as a bastion of counterculture, a view which has proceeded into the 21st century. According to a 2009 Pew Research Center study, Portland ranks as the 8th most popular American city, based on where people want to live.

Fallout 4

Fallout 4 is an action role-playing video game developed by Bethesda Game Studios and published by Bethesda Softworks. The fifth major installment in the Fallout series, the game was released worldwide on November 10, 2015 for Microsoft Windows, PlayStation 4, and Xbox One.

It is set in a post-apocalyptic Boston in the year 2287, 210 years after a devastating nuclear war, in which the player character emerges from an underground bunker known as Vault 111. Gameplay is similar to that of Fallout 3 and Fallout: New Vegas. The player completes various quests and acquires experience points to level up their character. With first- and third-person perspectives available, players can explore Fallout 4's open world setting at will, allowing nonlinear gameplay. Companions can accompany the player on their voyages to assist them in battles and help with scavenging. Players have the ability to construct and deconstruct buildings and items, and use them to build a settlement, which can attract and be inhabited by non-playable characters.

Google Play

Google Play or Google Play Store, and originally the Android Market, is a digital distribution platform operated by Google. It serves as the official app store for the Android operating system, allowing users to browse and download applications developed with the Android SDK and published through Google. Google Play also serves as a digital media store, offering music, magazines, books, movies, and television programs. It previously offered Google hardware devices for purchase until the introduction of a separate online hardware retailer, Google Store, on March 11, 2015.

Applications are available through Google Play either free of charge or at a cost. They can be downloaded directly to an Android or Google TV device through the Play Store mobile app, or by deploying the application to a device from the Google Play website. Many applications can be targeted to specific users based on a particular hardware attribute of their device, such as a motion sensor (for motion-dependent games) or a front-facing camera (for online video calling).
