Cricket and Technology: Dartfish

Back again with a cricket innovation: Dartfish
Dartfish is avery useful tool that allows a complete breakdown analysis of the player's action,ball trajectory and so on.The software uses digital video graphics to deliver instant visual feedback without disrupting the flow of match.It includes video analysis tools like SimulCam and StroMotion that enables the players as well as the coaches to make powerful technical,tactical and stastical analysis.
Simulcam composites two video sequences of live or archieved clips to illustrate at each and speed of the different players into a single integrated video sequence.StroMotion allows viewers to see live action unfold before their eyes in time and space by breaking the video images into a frame by frame sequence. The StroMotion technology is its ability to select certain images and break them into a series,thus editing the unnecessary images .

Cricket and technology: Hawk-eye

Another cricket innovation...the most useful and the most used...Hawk-eye Created by Paul Hawkins.This technological innovation uses sophesticated image processing techniques to track the trajectory of the ball once it has left the bowlers hand with the help of series of cameras placed all around the cricket stadium.In addition to resolving LBW decisions given by the umpire,it helps to accurately compare bowler's speed,line and length.Hawk-eye is used extensively by a lot of teams in cricket today due to its ease of use and also because it is visually appealing.However cricket is not the only sport where Hawk-eye is being used;it is equally popular in tennis where it helps to resolve controversial line-calls.It is also developing a system for the American baseball league for accurately tracking the flight of the bowler's pitches by using four to six dedicated cameras.

Cricket and technology: Stickometer

Cricket is in the air and not describing it technological factors would not be fair.
So lets start it with...
SNICKOMETER:
Thanks to the creator of this wonderful technical innovation:-Mr. Alan Plaskett
Snickometer helps the viewers as well as commentrators to judge if the umpire's decision in giving the batsmen out was correct or not.(This creation doesnt allow the viewer to jump out of their tv sets to kill the umpire)
Working:-
A high-sensitive microphone is placed very close to the off stump(may be thats why every mumble of the wicket keeper becomes a shout) and is coinnected to an oscilloscope which measures the sound waves of the oncoming ball.Whenever the batsmen nicks a ball,the oscilloscope trace goes wild.By watching the slow motion replay alongside this graph,you can determine whether the noise picked up by the microphone coincides with the ball passing the bat.
AND
Before:The oscilloscope trace After: The spike in the trace

before the ball makes contact when the ball makes contact
with the bat with the bat

From the above screenshot you can clearly see the difference in the oscilloscope trace.In the first image there is no spike in the trace which means the batsman did not nick the ball whereas the second image clearly shows the spike indicating that the bat has made contact with the ball.
