<div align="JUSTIFY">
<span style="font-size: large;">The engineering was initially utilized by Channel 4
amid a Test match in the middle of England and Pakistan on Lord's
Cricket Ground. It is utilized basically by the larger part of
broadcasting companies to track the trajectory of balls in flight.
The third umpire could take a gander at what the ball really did up
to the moment that it hit the batsman, however couldn't take a gander
at the anticipated flight of the ball after it hit the batsman. Its
real use in cricket television is in breaking down leg before wicket
choices, where the feasible way of the ball might be anticipated
forward, through the batsman's legs, to check whether it would have
hit the stumps. Counsel of the third umpire, for ordinary moderate
movement or Hawk-Eye, on leg before wicket choices, is as of now
endorsed in global cricket despite the fact that questions stay about
its correctness in cricket.</span></div>
<div align="JUSTIFY">
<span style="font-size: large;"><br /></span></div>
<div align="JUSTIFY">
<span style="font-size: large;">The Hawk-eye referral for LBW choice is focused
around three criteria:</span></div>
<ul style="text-align: left;">
<li><div align="JUSTIFY">
<span style="font-size: large;">Where the ball pitched
</span></div>
</li>
<li><div align="JUSTIFY">
<span style="font-size: large;">The area of contact with the leg of the batsman
</span></div>
</li>
<li><div align="JUSTIFY">
<span style="font-size: large;">The anticipated way of the ball past the
batsman
</span></div>
</li>
<li><div align="JUSTIFY">
<span style="font-size: large;">In every one of the three cases, negligible
calls bring about the on-field call being kept up.</span></div>
</li>
</ul>
<div align="JUSTIFY">
<span style="font-size: large;">Because of its real time scope of rocking the bowling
alley speed, the frameworks are likewise used to show conveyance
examples of bowler's conduct, for example, line and length, or
swing/turn data. At the end of an over, every one of the six
conveyances are frequently indicated all the while to demonstrate a
bowler's varieties, for example, slower conveyances, bouncers and
leg-cutters. A complete record of a bowler can additionally be
indicated throughout the span of a match. Batsmen likewise profit
from the examination of Hawk-Eye, as a record could be raised of the
conveyances batsmen scored from. These are frequently indicated as a
2-D silhouetted figure of a batsmen and color coded specks of the
balls confronted by the batsman. Data, for example, the accurate spot
where the ball pitches or pace of the ball from the bowler's hand can
additionally help in post-match dissection.</span></div>

Created by writer Stan Lee and artist Don Heck, the character first appeared as a villain in Tales of Suspense #57 (Sept. 1964) and later joined the Avengers in Avengers #16 (May 1965). He has been a prominent member of the team ever since. He was also ranked at #44 on IGN's Top 100 Comic Book Heroes list.<br />
<br />
Hawkeye is portrayed by Jeremy Renner in the Marvel Cinematic Universe, a shared fictional universe that is the setting of films produced by Marvel Studios. Renner first made a brief, uncredited cameo appearance as Hawkeye in Thor (2011) and later reprised the role in The Avengers (2012).</div>Ann Jeffhttp://www.blogger.com/profile/08853178476825869359noreply@blogger.com0tag:blogger.com,1999:blog-2439456076555378226.post-72755860756821426562011-08-22T00:10:00.001-07:002014-01-17T05:19:33.605-08:00Hawk-Eye<div dir="ltr" style="text-align: left;" trbidi="on">
Hawk-Eye is a complex computer system used in cricket, tennis and other sports to visually track the trajectory of the ball and display a record of its most statistically likely path as a moving image. In cricket and tennis, it is now part of the adjudication process. It was developed by engineers at Roke Manor Research Limited of Romsey, Hampshire in the UK, in 2001. A UK patent was submitted but withdrawn by Dr Paul Hawkins and David Sherry. Later, the technology was spun off into a separate company, Hawk-Eye Innovations Ltd., as a joint venture with television production company Sunset + Vine, which was bought outright by Sony in March 2011.<br />
<br />
All Hawk-Eye systems are based on the principles of triangulation using the visual images and timing data provided by at least four high-speed video cameras located at different locations and angles around the area of play. The system rapidly processes the video feeds by a high-speed video camera and ball tracker. A data store contains a predefined model of the playing area and includes data on the rules of the game.<br />
In each frame sent from each camera, the system identifies the group of pixels which corresponds to the image of the ball. It then calculates for each frame the 3D position of the ball by comparing its position on at least two of the physically separate cameras at the same instant in time. A succession of frames builds up a record of the path along which the ball has travelled. It also "predicts" the future flight path of the ball and where it will interact with any of the playing area features already programmed into the database. The system can also interpret these interactions to decide infringements of the rules of the game.<br />
<br />
The system generates a graphic image of the ball path and playing area, which means that information can be provided to judges, television viewers or coaching staff in near real time.<br />
<br />
The pure tracking system is combined with a backend database and archiving capabilities so that it is possible to extract and analyse trends and statistics about individual players, games, ball-to-ball comparisons, etc.<br />
