Tracking (hunting)
Tracking in hunting and ecology is the science and art of observing animal tracks and other signs, with the goal of gaining understanding of the landscape and the animal being tracked (the "quarry"). A further goal of tracking is the deeper understanding of the systems and patterns that make up the environment surrounding and incorporating the tracker. The practice of tracking may focus on, but is not limited to, the patterns and systems of the local animal life and ecology. Trackers must be able to recognize and follow animals through their tracks, signs, and trails, also known as spoor. Spoor may include tracks, scat, feathers, kills, scratching posts, trails, drag marks, sounds, scents, marking posts, feeding signs, the behavior of other animals, habitat cues, and any other clues about the identity and whereabouts of the quarry. The skilled tracker is able to discern these clues, recreate what transpired on the landscape, and make predictions about the quarry. The track ...

Eye Tracking
Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the visual system, in psychology, in psycholinguistics, marketing, as an input device for human-computer interaction, and in product design. In addition, eye trackers are increasingly being used for assistive and rehabilitative applications such as controlling wheelchairs, robotic arms, and prostheses. Recently, eye tracking has been examined as a tool for the early detection of autism spectrum disorder. There are several methods for measuring eye movement, with the most popular variant using video images to extract eye position. Other methods use search coils or are based on the electrooculogram. History In the 1800s, studies of eye movement were made using direct observations. For example, Louis Émile Javal observed in 187 ...

Animal Migration Tracking
Animal migration tracking is used in wildlife biology, conservation biology, ecology, and wildlife management to study animals' behavior in the wild. One of the first techniques was bird banding, placing passive ID tags on birds legs, to identify the bird in a future catch-and-release. Radio tracking involves attaching a small radio transmitter to the animal and following the signal with a RDF receiver. Sophisticated modern techniques use satellites to track tagged animals, and GPS tags which keep a log of the animal's location. With the Emergence of IoT the ability to make devices specific to the species or what is to be tracked is possible. One of the many goals of animal migration research has been to determine where the animals are going; however, researchers also want to know why they are going "there". Researchers not only look at the animals' migration but also what is between the migration endpoints to determine if a species is moving to new locations based on food dens ...

Video Tracking
Video tracking is the process of locating a moving object (or multiple objects) over time using a camera. It has a variety of uses, some of which are: human-computer interaction, security and surveillance, video communication and compression, augmented reality, traffic control, medical imaging and video editing. Video tracking can be a time-consuming process due to the amount of data that is contained in video. Adding further to the complexity is the possible need to use object recognition techniques for tracking, a challenging problem in its own right. Objective The objective of video tracking is to associate target objects in consecutive video frames. The association can be especially difficult when the objects are moving fast relative to the frame rate. Another situation that increases the complexity of the problem is when the tracked object changes orientation over time. For these situations video tracking systems usually employ a motion model which describes how the image ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Tracking System
A vehicle tracking system combines the use of automatic vehicle location in individual vehicles with software that collects these fleet data for a comprehensive picture of vehicle locations. Modern vehicle tracking systems commonly use GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle location technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software. Urban public transit authorities are an increasingly common user of vehicle tracking systems, particularly in large cities. Active versus passive tracking Several types of vehicle tracking devices exist. Typically they are classified as "passive" and "active". "Passive" devices store GPS location, speed, heading and sometimes a trigger event such as key on/off, door open/closed. Once the vehicle returns to a predetermined point, the device is removed and the data downloaded to a computer for evaluation. Passive systems includ ...

Positional Tracking
In 3D human-computer interaction, positional tracking, also called pose tracking, is a process that tracks the position and/or orientation of head-mounted displays, controllers, or other input devices within Euclidean space. Pose tracking is often referred to as 6DOF tracking, for the six degrees of freedom in which the objects are often tracked. In some consumer GPS systems, orientation data is added additionally using magnetometers, which give partial orientation information, but not the full orientation that pose tracking provides. In VR, it is paramount that pose tracking is both accurate and precise so as not to break the illusion of a being in virtual world. Several methods of tracking the position and orientation (pitch, yaw and roll) of a display and any associated objects or devices have been developed to achieve this. Many methods utilize sensors which repeatedly record signals from transmitters on or near the tracked object(s), and then send that data to the comput ...

Environmental Investment Organisation
The Environmental Investment Organisation (EIO) is a UK-based not-for-profit body dedicated to researching, proposing and implementing solutions to climate change. It has developed the ''Environmental Tracking'' (ET) concept, rebranded by ET Index Research in 2016 to Engaged Tracking, into two separate components known as the ET Carbon Rankings and the ET Index Series. The ET Carbon Rankings rate companies based on their greenhouse gas emissions intensity and transparency. The ET Low Carbon & Fossil Free Index Series, which are based on the rankings, provide investors with a tool to incentivise companies to lower emissions while reducing their exposure to potential future carbon 'price shocks'. Origins The EIO was set up as in 1996 by London School of Economics alumnus, Michael Gill, as a parallel body to the LSE Environmental Initiatives Network (EIN). Michael Gill co-founded the LSE EIN with Janos Abel and was the EIN's first elected chairman stepping down in 2003 to become the ...

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, vo ...

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 for data fusion. 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 coordinate system, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
