Detailed Description

template<class TFrameType>
class itk::VideoStream< TFrameType >

A DataObject that holds a buffered portion of a video.

The function of VideoStream is to provide an Image-specific subclass of TemporalDataObject. It provides several convenient typedefs to get common attributes of the frames. Additionally, the VideoStream caches meta information (lagest/requested/buffered spatial regions, origin, spacing, and direction) about all frames in the video, even those not currently buffered. This is done primarily in order to allow the meta data to be set before the frame is buffered.

void itk::VideoStream< TFrameType >::Allocate

(

)

Allocate memory for the buffered spatial region of each frame in the buffered temporal region. This assumes that all frames in the buffered temporal region have been initialized and that the buffered spatial region has been set for each of these frames. A typical setup would look like:

// Set the temporal regions
TemporalRegionType temporalRegion;
temporalRegion.SetFrameStart( 0 );
temporalRegion.SetFrameDuration( 3 );
video->SetLargestPossibleTemporalRegion( temporalRegion );
video->SetRequestedTemporalRegion( temporalRegion );
video->SetBufferedTemporalRegion( temporalRegion );

// Initialize all frames in the buffered temporal region
video->InitializeEmptyFrames();

// Set the buffered spatial region for each frame
SpatialRegionType bufferedSpatialRegion;
SpatialRegionType::SizeType size;
SpatialRegionType::IndexType start;
size[0] = 50;
size[1] = 40;
start.Fill( 0 );
bufferedSpatialRegion.SetSize( size );
bufferedSpatialRegion.SetIndex( start );
video->SetAllBufferedSpatialRegions( bufferedSpatialRegion );

// Allocate memory for the frames
video->Allocate();

virtual::itk::LightObject::Pointer itk::VideoStream< TFrameType >::CreateAnother ( void  ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Get the frame for the given frame number. Internally, we always leave the Head of the ring buffer in place and just use the frame number as an offset. This allows all references to frames to be processed by an explicit frame number rather than a potentially confusing offset.

Graft the data and information from one VideoStream to this one. This just copies the meta information using TemporalProcessObject's Graft then sets the internal RingBuffer pointer to point to the same buffer used by the other VideoStream.

void itk::VideoStream< TFrameType >::InitializeEmptyFrames

(

)

Initialize any empty frames. This method makes sure that the frame buffer is large enough to hold the number of frames needed for the buffered temporal region. It goes through the necessary number of frames making sure that each one has been initialized. When allocating space for frames, this method should be called first, followed by setting the spatial regions on each frame, before Allocate is called.
