Detailed Description

TemporalProcessObject implements a ProcessObject for the itk pipeline with the notion of a temporal region.

TemporalProcessObject acts as a pass-through in the inheritance tree in order to require that subclasses properly implement handeling of temporal regions. The key parameters of a temporal process object are:

m_UnitInputNumberOfFrames m_UnitOutputNumberOfFrames m_FrameSkipPerOutput m_InputStencilCurrentFrameIndex

These parameters are protected by default so that the filter writer can choose which to expose and which to keep constant. For a full explanation of each parameter, see the individual comments with their declarations. Subclasses of TemporalProcessObject must implement one of the following:

GenerateData() TemporalStreamingGenerateData()

By default, GenerateData will split the requested temporal region of the input and output temporal data objects into sub-requests of unit input and unit output size. For example, if the output requests 3 frames and the filter has unit input size of 2 and unit output size of 1, GenerateData will produce 3 sub-requests that each require the input to provide 2 frames. Using this default behavior, TemporalStreamingGenerateData must be implemented and can assume that the RequestedTemporalRegion on the input and output are unit size. If the temporal streaming behavior is not desired, GenerateData can be implemented to directly handle the full output requested temporal region in a single pass.

Member Function Documentation

virtual void itk::TemporalProcessObject::AfterTemporalStreamingGenerateData ( )

Method that gets called by GenerateData after TemporalStreamingGenerateData. Subclasses can override this method to provide post-processing for the data after producing the requested output temporal region.

Definition at line 204 of file itkTemporalProcessObject.h.

virtual void itk::TemporalProcessObject::BeforeTemporalStreamingGenerateData ( )
inlineprotectedvirtual

Method that gets called by GenerateData before TemporalStreamingGenerateData. Subclasses can override this method to provide pre-processing for the data before splitting up the requested output temporal region.

virtual void itk::TemporalProcessObject::EnlargeOutputRequestedRegion ( DataObject output)
overridevirtual

Override EnlargeOutputRequestedRegion, GenerateOutputRequestedRegion, and GenerateInputRequestedRegion to handle temporal regions

Reimplemented from itk::ProcessObject.

virtual void itk::TemporalProcessObject::EnlargeOutputRequestedTemporalRegion ( TemporalDataObject output)
protectedvirtual

Explicitly handle temporal regions in EnlargeRequestedRegion. The default implementation makes sure that the output requested temporal region is contained in the buffered temporal region or has a duration that is a multiple of the unit output number of frames

virtual void itk::TemporalProcessObject::GenerateData ( )
overridevirtual

Override GenerateData to do temporal region streaming. This is analogous to the ThreadedGenerateData system implemented in ImageSource, but it functions slightly differently. Since most temporal processes are going to to need more input frames than they produce output frames for a single operation, we cannot use the same model as spatial streaming which assumes that the input requested region is fully populated before producing any output. Instead, once we have split the requested output region, we reset the requested temporal region of the input to each input requested temporal sub-region (in sequence) and re-propagate the temporal region request up the pipeline.

Reimplemented from itk::ProcessObject.

virtual TemporalRegion itk::TemporalProcessObject::GenerateDefaultLargestPossibleTemporalRegion ( )
protectedvirtual

Generate a default LargestPossibleRegion. This is used by temporal process objects that have no input. The default implementation starts at frame 0 and has infinite duration.

virtual void itk::TemporalProcessObject::GenerateInputRequestedRegion ( )
overridevirtual

What is the input requested region that is required to produce the output requested region? By default, the largest possible region is always required but this is overridden in many subclasses. For instance, for an image processing filter where an output pixel is a simple function of an input pixel, the input requested region will be set to the output requested region. For an image processing filter where an output pixel is a function of the pixels in a neighborhood of an input pixel, then the input requested region will need to be larger than the output requested region (to avoid introducing artificial boundary conditions). This function should never request an input region that is outside the the input largest possible region (i.e. implementations of this method should crop the input requested region at the boundaries of the input largest possible region).

Reimplemented from itk::ProcessObject.

Reimplemented in itk::VideoToVideoFilter< TInputVideoStream, TOutputVideoStream >, itk::VideoToVideoFilter< itk::VideoStream< TImageToImageFilter::InputImageType >, itk::VideoStream< TImageToImageFilter::OutputImageType > >, and itk::VideoToVideoFilter< TVideoStream, TVideoStream >.

virtual void itk::TemporalProcessObject::GenerateInputRequestedTemporalRegion ( )
protectedvirtual

Explicitly handle temporal regions in GenerateInputRequestedRegion. The default implementation sets the requested temporal region on the input to start at m_FrameSkipPerOutput times the start frame of the requested output temporal region with the duration needed to produce the entire requested output.

NOTE: This default propagation will be overwritten during the UpdateOutputData phase by the temporal streaming mechanism if a subclass implements TemporalStreamingGenerateData, but this propagation is provided so that subclasses which directly implement GenerateData will work correctly.

virtual void itk::TemporalProcessObject::GenerateOutputRequestedRegion ( DataObject output)
overridevirtual

Given one output whose requested region has been set, how should the requested regions for the remaining outputs of the process object be set? By default, all the outputs are set to the same requested region. If a filter needs to produce different requested regions for each output, for instance an image processing filter producing several outputs at different resolutions, then that filter may override this method and set the requested regions appropriatedly.

Note that a filter producing multiple outputs of different types is required to override this method. The default implementation can only correctly handle multiple outputs of the same type.

Reimplemented from itk::ProcessObject.

Reimplemented in itk::VideoToVideoFilter< TInputVideoStream, TOutputVideoStream >, itk::VideoToVideoFilter< itk::VideoStream< TImageToImageFilter::InputImageType >, itk::VideoStream< TImageToImageFilter::OutputImageType > >, and itk::VideoToVideoFilter< TVideoStream, TVideoStream >.

virtual void itk::TemporalProcessObject::GenerateOutputRequestedTemporalRegion ( TemporalDataObject output)
protectedvirtual

Explicitly handle temporal regions in GeneratOutputRegion. The default implementation checks to see if a request is currently set and if not, it sets the requested temporal region to match the largest possible temporal region

Note: If the largest possible temporal duration has infinite duration, the requested temporal region will be set to have duration 1.

virtual std::vector<TemporalRegion> itk::TemporalProcessObject::SplitRequestedTemporalRegion ( )
protectedvirtual

Split the output's RequestedTemporalRegion into the proper number of sub-regions. By default it is assumed that each sub-region processed should be generated using the set of input frames starting one frame forward in time from the previous sub-region. To change this, set FrameSkipPerOutput to something other than 1. Positive indicates forward in time while negative indicates backward in time. The set of returned TemporalRegion objects is the set of temporal regions that are needed as input to generate the entire output requested region

virtual void itk::TemporalProcessObject::TemporalStreamingGenerateData ( )
virtual

TemporalStreamingGenerateData is in charge of producing output for a single portion of the output requested temporal region. This is where the body of the process will take place. Subclasses that handle spatial data (such as video frames) may instead use this function to split the requested spatial region and process the spatial sub-regions using the mechanism implemented in ImageBase for multithreading.

Reimplemented in itk::VideoFileWriter< TInputVideoStream >, itk::VideoSource< TOutputVideoStream >, itk::VideoSource< TVideoStream >, itk::VideoSource< itk::VideoStream< TImageToImageFilter::OutputImageType > >, itk::VideoFileReader< TOutputVideoStream >, and itk::ImageFilterToVideoFilterWrapper< TImageToImageFilter >.

virtual void itk::TemporalProcessObject::UpdateOutputData ( DataObject output)
overridevirtual

Override ProcessObject's implementation of UpdateOutputData. This is necessary because by default ProcessObject propagates the call to its inputs before calling GenerateData. This doesn't work here because we need to adjust the requested temporal region of our inputs before calling their UpdateOutputData methods

NOTE: Subclasses that don't use the temporal streaming process must override this function to call the version implemented in ProcessObject

Code: this->ProcessObject::UpdateOutputData( output )

Reimplemented from itk::ProcessObject.

virtual void itk::TemporalProcessObject::UpdateOutputInformation ( )
overridevirtual

The default implementation of UpdateOutputInformation to handle temporal regions will compute the proper size of the output largest possible temporal region based on the largest possible temporal region of the input, the unit input/output sizes for the process, and the number of frames skipped per output

Reimplemented from itk::ProcessObject.
