#include <itkVideoStream.h>

Detailed Description

template<typename 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 (largest/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.

◆ VideoStream()

template<typename TFrameType >
itk::VideoStream< TFrameType >::VideoStream ( )

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

◆ ~VideoStream()

template<typename TFrameType >

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

Member Function Documentation

◆ Allocate()

template<typename TFrameType >
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();

◆ GetFrame() [1/2]

template<typename TFrameType >
FrameType* itk::VideoStream< TFrameType >::GetFrame ( SizeValueType  frameNumber)

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.

◆ GetFrame() [2/2]

template<typename TFrameType >
const FrameType* itk::VideoStream< TFrameType >::GetFrame ( SizeValueType  frameNumber) const

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()

template<typename TFrameType >
void itk::VideoStream< TFrameType >::Graft ( const DataObject *  data)
overridevirtual

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.

Reimplemented from itk::TemporalDataObject.

◆ InitializeEmptyFrames()

template<typename TFrameType >
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.

◆ New()

◆ PrintSelf()

template<typename TFrameType >

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

◆ FrameDimension

template<typename TFrameType >
constexpr unsigned int itk::VideoStream< TFrameType >::FrameDimension = FrameType::ImageDimension
staticconstexpr

Access the spacial dimensionality of the frames

Definition at line 76 of file itkVideoStream.h.

◆ m_BufferedSpatialRegionCache

template<typename TFrameType >
SpatialRegionMapType itk::VideoStream< TFrameType >::m_BufferedSpatialRegionCache {}
protected

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

Definition at line 360 of file itkVideoStream.h.

◆ m_DirectionCache

template<typename TFrameType >
DirectionMapType itk::VideoStream< TFrameType >::m_DirectionCache {}
protected

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

Definition at line 365 of file itkVideoStream.h.

◆ m_LargestPossibleSpatialRegionCache

template<typename TFrameType >
SpatialRegionMapType itk::VideoStream< TFrameType >::m_LargestPossibleSpatialRegionCache {}
protected

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

Definition at line 358 of file itkVideoStream.h.

◆ m_NumberOfComponentsPerPixelCache

template<typename TFrameType >
NumberOfComponentsPerPixelMapType itk::VideoStream< TFrameType >::m_NumberOfComponentsPerPixelCache {}
protected

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

Definition at line 367 of file itkVideoStream.h.

◆ m_OriginCache

template<typename TFrameType >
PointMapType itk::VideoStream< TFrameType >::m_OriginCache {}
protected

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

Definition at line 366 of file itkVideoStream.h.

◆ m_RequestedSpatialRegionCache

template<typename TFrameType >
SpatialRegionMapType itk::VideoStream< TFrameType >::m_RequestedSpatialRegionCache {}
protected

These maps are used to cache a mapping between frame number and spatial region. This is done because frames will often not be in actual existence at the time when the region gets set.

Definition at line 359 of file itkVideoStream.h.

◆ m_SpacingCache

template<typename TFrameType >
SpacingMapType itk::VideoStream< TFrameType >::m_SpacingCache {}
protected

These maps cache a mapping between frame number and the meta data for origin, spacing, direction, and number of components per pixel
