Camera Calibration

Camera Calibration : Shows the use of the camera calibration method within EMGU,

• Capture()
  

• CalibrateCamera()
  

• FindChessboardCorners()
  

• IntrinsicCameraParameters
  

• ExtrinsicCameraParameters
  

Stereo Imaging : Shows the use of the camera calibration StereoCalibrate method within EMGU,

• FindChessboardCorners()
  

• StereoCalibrate()
  

• cvStereoRectify()
  

• IntrinsicCameraParameters

Capture

Capture: Camera : Shows the use of the camera capture method to acquire images from a web cam or alternative connected device. This example uses a independent thread to deal with acquiring frames from the device.

• Capture()
  

• RetrieveBgrFrame()
  

• RetrieveGrayFrame()
  

• GetCaptureProperty()
  

• SetCaptureProperty()
  

Capture: Camera - Legacy : Shows the use of the older use of the camera capture method to acquire images from a web cam or alternative connected device. This example uses the Application.Idle event to deal with acquiring frames from the device. This method is dependant on processing the form functions first.

• Capture()
  

• RetrieveBgrFrame()
  

• RetrieveGrayFrame()
  

• GetCaptureProperty()
  

• SetCaptureProperty()
  

Capture: Video Files Capture : Shows the use of the capture method to load videos save them from a web cam and look at individual frames. It also demostrates the use of the VideoWriter class.

• Capture()
  

• VideoWriter
  

• RetrieveBgrFrame()
  

• RetrieveGrayFrame()
  

• GetCaptureProperty()
  

• SetCaptureProperty()
  

• WriteFrame()
  

Capture: Kinect : Shows the use of the camera capture method to acquire images from a Microsoft Kinect Device.

In Progress

• KinectCapture()
  

• RetrieveBgrFrame()

HistogramShows the use of C# histogram method

In Progress

Image

Background ImageShows the use of the RunningAvg() to forms a background image of stationary objects within a camera field of view. This can be used for motion tracking purposes with background subtraction.

• AbsDiff()
  

• RunningAvg()
  

• ThresholdBinary()
  

• ToBitmap()
  

Compare Images: DifferenceShows the use of the AbsDiff() to compare two images, in this case the current frame and previous frame from a web camera. This can be used for motion tracking purposes. This example can be combined with the Background Image example.

• AbsDiff()
  

• ThresholdBinary()
  

• FindContours()
  

• ToBitmap()
  

VideoWriter

See Capture: Video Files Capture : Shows the use of the capture method to load videos save them from a web cam and look at individual frames. It also demostrates the use of the VideoWriter class.

• VideoWriter
  

• WriteFrame()
