Vision System what is it?

• Just because a camera is used, it does not make
  it a vision system.
• A vision system would include an imaging device,
  some processing, a set of algorithms and some
  decisions made based on sensed image.

3
Not a Vision System

• Security Cameras statistics indicates that high
  percentage of crimes happens in open places such
  as parking lots, especially late in night when it
  gets darker, so by installing cameras you would
  assure that you would pick any clue that would
  lead you to the persons who have done that act.

Hall of Fame - Applications

• Real-time 3-dimensional acquisition and tracking
  of objects
• http//www.tyzx.com/Technology.shtml
• This company makes a vision system which has the
  ability to interpret a three dimensional scene.
  Their system, the DeepSea Development System,
  has been used to successfully demonstrate a
  number of applications such as person tracking,
  head and hand tracking, virtual peripherals, and
  automotive occupant sensing. 
• The system uses something called stereo vision,
  which simultaneously combines two captured images
  to determine distance, object size and shapes,
  anywhere in the scene.

Hall of Fame - Application

• Automated Egg sorting uses computer vision to
  sort chicken eggs by gender, to ensure breeding
  of uniform body weight. A chemical is used that
  reacts with female hormone, producing a vivid
  yellow. This is later determined by the vision
  sensor system which analyses 210 eggs per camera,
  every three seconds. A synopsis of there process
  is as follows instead of using RGB, Comdex
  developed vision algorithms for
  hue-saturation-intensity color planes, because of
  this it was able to look at the wavelengths of
  color and the clarity in a wide variety of
  lighting situations, and regardless of color
  saturation.

• when a person is watching hockey sometimes the
  hockey puck is illuminated with in red. This
  helps viewers see the puck. (Also used in
  NASCAR).
• Medical Endoscopy

• Digital Camera
• One real world application is tracking of work
  place activity. By mounting video cameras
  around an office and combined with facial
  recognition software it would be possible to know
  what each employee was doing at any given time.
  Another real world application comes from
  Hollywood, it could be phrased as real time
  motion capture. A human actor wears a suit with
  fixed points on it, usually ping pong balls. The
  actor does all the required motions on film and
  then it is digitized and a digital character can
  then move in the same exact way the actor did.
• Night vision goggles

• Automation scripts for companies websites
  testing a script goes through every page, to
  every URL, and makes sure each page looks exactly
  the way it suppose to look, i.e. certain text
  and/or images appear in the right place and in
  the right format, etc.

Hall of Fame - Proposed

• Learning to play the guitar - When someone is
  learning to play the guitar a lot of time they
  have a hard time with holding the guitar properly
  and learning the proper technique. Because of
  this I am proposing a system that would allow for
  an expert in the area (i.e. a guitar teacher) to
  tape a song that they would like their student to
  learn and the camera would take pictures based on
  the time signature of the piece. After this is
  done the image will be processed and broken down
  into finger positions, technique and so on.

Hall of Fame

• Another way I feel that computer vision could
  affect the sports world would be in the
  recreation of nine ball billiards. The idea is
  to use geometry to configure a path a ball needs
  to be on to be pocketed. The path will then be
  shown on a screen so that the player could use it
  as a tool to make his next shot.

• There may be a few ways that computer vision
  could reduce auto accidents. We could use
  computer vision to create an Automobile accident
  prevention system. We would need to use some
  kind of eye or camera mounted on a car. We
  would also need the electronics that would
  perform some kind of action if it were processed
  that the car was in trouble. First off, a good
  deal of accidents occur when the driver is not
  paying attention to the road, or traffic in front
  of them. Our vision system could be programmed to
  sound an auditory alarm when our vehicle is
  approaching an object or another car too fast.

Hall of Fame

• In a game of chess against a computer with a
  physical chess set, it would be nice if the
  computer could move its own piece. It would
  need to have both sensors and actuators. The
  sensors would take a picture of the physical
  board and then analyze its content. The content
  would then be mapped to a matrix. It would then
  be able to process its answer and move the piece
  on the physical board with a magnet.

Hall of Fame

• On a battle field, a tank might have a difficult
  time distinguishing a small target from the rest
  of the landscape. The tank could contain a
  camera that would take video of the landscape.
  This video would then be processed to look for
  movement. The areas that have movement can then
  be analyzed for shapes. This could then be
  placed on a screen of possible targets that could
  be compared to the real photo for the real
  possibility of an enemy. Then the tank would not
  be firing on a target that was not an enemy but
  rather a tree in the wind.

• Airline security will enter the information about
  pilot and co-pilot into cockpit computer
  including their photographs. During flight the
  cockpit computer will identify pilot and co-pilot
  using face recognition. Identification process
  will kick off upon any movement in cockpit or at
  fixed interval. Face recognition can yield
  instant results, verifying the identity of a
  pilot, co-pilot or crew member instantly and
  checking through computer records for possible
  matches quickly, automatically and reliably. If
  computer fails to recognize any of the faces of
  pilot or co-pilot, it will send distress signal
  to the nearest Air Traffic Control Tower. Or if
  there is prolonged presence of any person in
  cockpit other than crew member, it will send
  signal about it to the nearest Air Traffic
  Control Tower.

• At the entrance to the Cedar Dell apartments on
  campus there is a guardhouse that is usually
  occupied by a student at nights. The students
  job is to make sure every car entering the Cedar
  Dell has a Cedar Dell parking sticker. Instead
  of using a student to do this, a scanner could be
  used to read a barcode off of a passing cars
  sticker in front of the guardhouse and open a
  gate at the rear of the guardhouse to the Cedar
  Dell for cars with valid parking stickers. This
  would be much like the Easy Pass system being
  used by the mass pike. A system like this would
  also make it easier to collect data on traffic
  flow around the campus, which could prove useful
  with future campus additions such as parking
  lots, dormitory and road construction.

Hall of Shame - Proposed

• An interesting vision system might be a system
  that constantly monitors and charts stars and
  star systems. This system would be need a
  telescope or perhaps multiple telescopes to be
  effective. It could actually compile data from
  multiple points on the earth to get a larger
  picture and different points of view. This
  system would monitor stars and be able to tell
  their composition and lifespan by the light
  spectrums they give off. It would constantly be
  charting stars and figuring distances by constant
  monitoring. This system could perhaps identify
  planets and star systems we have not yet been
  able to identify. Having this knowledge could
  help scientists decide which areas of space they
  wished to further investigate. It could also be
  tweaked to closely monitor closer planets, ones
  in our solar system. Through the use of images
  and some reasoning ability, it could help to
  determine the history of planets and their states
  and perhaps even make predictions about their
  future, but it would need to be tied to an expert
  system or have some logic involved to make these
  decisions.

• For security system
• When you get on airplane you have to go through
  the security gate. Whenever the gate alarms, then
  securities check your body using detectors.
  However, this way can be insufficient because one
  crime could bring bombs that were equipped in
  shoes to the airplane. A vision system could be
  used to detect where criminals have weapons such
  as guns in their cloth or shoes.
• Solution
• Use X-ray or magnetic field devise or sensors
  within the gate, for instance the gate can be a
  same thing as the security gate used in airport,
  then show the body image data collected from
  sensors on the screen. This solution is actually
  in used at any airport to check baggage, but it
  is not used to body detection.
