Match Moving
In visual effects, match moving is a technique that allows the insertion of computer graphics into live-action footage with correct position, scale, orientation, and motion relative to the photographed objects in the shot. The term is used loosely to describe several different methods of extracting camera motion information from a motion picture. Sometimes referred to as motion tracking or camera solving, match moving is related to rotoscoping and photogrammetry. Match moving is sometimes confused with motion capture, which records the motion of objects, often human actors, rather than the camera. Typically, motion capture requires special cameras and sensors and a controlled environment (although recent developments such as the Kinect camera and Apple's Face ID have begun to change this). Match moving is also distinct from motion control photography, which uses mechanical hardware to execute multiple identical camera moves. Match moving, by contrast, is typically a software-base ...

Tracking (documentary)
''Tracking'' (1994) is a documentary about the band Phish and the recording of the album '' Hoist''. It is directed by the band's bass player, Mike Gordon, who wrote, for the VHS packaging: :While in the studio recording the album 'Hoister' (sic) I sported a video camera. Sometimes I pushed the record button. Others, the stop. Alas, I edited. Using machines small yet sweet, I assembled ''Tracking''. This isn't about railroad tracks or stuffing things up the tender nostril. It's about 48 tracks of sound, adjacent on strips of plastic. Like mixing lilac petals, coriander, chunks of butter, and fennel into a soup. ''Tracking'' is the recording of different sounds, adjacent on strips of plastic. . . . Many of the musicians on the album, Alison Krauss, Béla Fleck, and actor Jonathan Frakes, are shown recording tracks that eventually wound up on the album. The documentary is approximately 25 minutes long and was produced by Cactus Films. Personnel Phish :Trey Anastasio - guitars, ...

Multitrack Recording
Multitrack recording (MTR), also known as multitracking or tracking, is a method of sound recording developed in 1955 that allows for the separate recording of multiple sound sources or of sound sources recorded at different times to create a cohesive whole. Multitracking became possible in the mid-1950s when the idea of simultaneously recording different audio channels to separate discrete "tracks" on the same reel-to-reel tape was developed. A "track" was simply a different channel recorded to its own discrete area on the tape whereby their relative sequence of recorded events would be preserved, and playback would be simultaneous or synchronized. A multitrack recorder allows one or more sound sources to different tracks to be simultaneously recorded, which may subsequently be processed and mixed separately. Take, for example, a band with vocals, guitars, a keyboard, bass, and drums that are to be recorded. The singer's microphone, the output of the guitars and keys, and eac ...

Mass Surveillance
Mass surveillance is the intricate surveillance of an entire or a substantial fraction of a population in order to monitor that group of citizens. The surveillance is often carried out by local and federal governments or governmental organizations, such as organizations like the NSA, but it may also be carried out by corporations (either on behalf of governments or at their own initiative). Depending on each nation's laws and judicial systems, the legality of and the permission required to engage in mass surveillance varies. It is the single most indicative distinguishing trait of totalitarian regimes. It is also often distinguished from targeted surveillance. Mass surveillance has often been cited as necessary to fight terrorism, prevent crime and social unrest, protect national security, and control the population. At the same time, mass surveillance has equally often been criticized for violating privacy rights, limiting civil and political rights and freedoms, and being il ...

Surveillance
Surveillance is the monitoring of behavior, many activities, or information for the purpose of information gathering, influencing, managing or directing. This can include observation from a distance by means of electronic equipment, such as closed-circuit television (CCTV), or interception of electronically transmitted information like Internet traffic. It can also include simple technical methods, such as Human intelligence (intelligence gathering), human intelligence gathering and postal interception. Surveillance is used by citizens for protecting their neighborhoods. And by governments for intelligence gathering - including espionage, prevention of crime, the protection of a process, person, group or object, or the investigation of crime. It is also used by criminal organizations to plan and commit crimes, and by businesses to Industrial espionage, gather intelligence on criminals, their competitors, suppliers or customers. Religious organisations charged with detecting he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missile Guidance
Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion. History The concept of unmanned guidance originated at least as early as World War I, with the idea of remotely guiding an airplane bomb onto a target, such as the systems developed for the R.F.C. World War I Drone Weapons, first powered drones by Archibald Low (The Father of Radio Guidance). In World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tracking Transmitter
A tracking transmitter broadcasts a radio signal which can be detected by a directional antenna (typically a Radio Direction Finder.) By rotating the antenna one can determine the direction the signal lies in and of course whatever it may be attached to. The EPIRB is an example of a similar device. It is commonly used in model rocketry and remote control aircraft to locate lost equipment. See also * Homing beacon * Emergency locator beacon An emergency locator beacon is a radio beacon, a portable battery powered radio transmitter, used to locate airplanes, vessels, and persons in distress and in need of immediate rescue.

Tracking System
A tracking system, also known as a locating system, is used for the observing of persons or objects on the move and supplying a timely ordered sequence of location data for further processing. It is important to be aware of human tracking, further details are listed below. Applications A myriad of tracking systems exists. Some are 'lag time' indicators, that is, the data is collected after an item has passed a point for example a bar code or choke point or gate. Others are 'real-time' or 'near real-time' like Global Positioning Systems (GPS) depending on how often the data is refreshed. There are bar-code systems which require items to be scanned and automatic identification (RFID auto-id). For the most part, the tracking worlds are composed of discrete hardware and software systems for different applications. That is, bar-code systems are separate from Electronic Product Code (EPC) systems, GPS systems are separate from active real time locating systems or RTLS for exampl ...

Radar Tracker
A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into Track (navigation), tracks. It is particularly useful when the radar system is reporting data from several different targets or when it is necessary to combine the data from several different radars or other sensors. Role of the radar tracker A classical rotating air surveillance radar system detects target echoes against a background of noise. It reports these detections (known as "plots") in polar coordinates representing the range and bearing of the target. In addition, noise in the radar receiver will occasionally exceed the detection threshold of the radar's Constant false alarm rate detector and be incorrectly reported as targets (known as false alarms). The role of the radar tracker is to monitor consecutive updates from the radar system (which typically occur once every few seconds, as the antenna rot ...

Video Tape Tracking
In a video tape recorder, tracking is a calibration adjustment which ensures that the spinning playback head is properly aligned with the helical scan signal written onto the tape. In the case of VHS, a linear control track A control track is a track that runs along an outside edge of a standard analog videotape (including VHS). The control track encodes a series of pulses, each pulse corresponding to the beginning of each frame. This allows the video tape player t ... at the tape's lower edge holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback and to get the rotating heads exactly on their helical tracks rather than having them end up somewhere between two adjacent tracks. However, the exact distance between the rotating video head and the fixed head reading the linear track can vary by a couple of micrometers between machines due to manufacturing tolerances, so most machines offer a manual or automatic trac ...

Toe (automotive)
In automotive engineering, toe, also known as tracking, is the symmetric angle In Euclidean geometry, an angle is the figure formed by two Ray (geometry), rays, called the ''Side (plane geometry), sides'' of the angle, sharing a common endpoint, called the ''vertex (geometry), vertex'' of the angle. Angles formed by two ... that each wheel makes with the longitudinal axis of the vehicle, as a function of static geometry, and kinematic and compliant effects. This can be contrasted with steer (automotive), steer, which is the antisymmetric angle, i.e. both wheels point to the left or right, in parallel (roughly). Negative toe, or toe out, is the front of the wheel pointing away from the centreline of the vehicle. Positive toe, or toe in, is the front of the wheel pointing towards the centreline of the vehicle. Historically, and still commonly in the United States, toe was specified as the linear difference (either inches or millimeters) of the distance between the two fron ...
