Detailed Description

template<typename TInputImage>
class itk::ImageSink< TInputImage >

ImageSink is the base class for process objects which consume image data. This class defaults to having at least one input of the templated image type. The framework enables derived algorithms to stream the input image as it's being consumed by the algorithm.

The framework provides multi-threading of the streamed image regions. The input image's pipeline is updated multiple times with the streaming requested regions, then the fulfilled requested region are split again for multi-threading.

By default, the NumberOfStreamDivisions is 1 (no streaming). Derived implementations must change the access specification for this method to be public to expose the streaming feature.

protectedpure virtual

◆ Update()

template<typename TInputImage>
void itk::ImageSink< TInputImage >::Update ( )
overridevirtual

Bring this filter up-to-date.

Update() checks modified times against last execution times, and re-executes objects if necessary. A side effect of this method is that the whole pipeline may execute in order to bring this filter up-to-date. This method updates the currently prescribed requested region. If no requested region has been set on the output, then the requested region will be set to the largest possible region. Once the requested region is set, Update() will make sure the specified requested region is up-to-date. This is a confusing side effect to users who are just calling Update() on a filter. A first call to Update() will cause the largest possible region to be updated. A second call to Update() will update that same region. If a modification to the upstream pipeline cause a filter to have a different largest possible region, this second call to Update() will not cause the output requested region to be reset to the new largest possible region. Instead, the output requested region will be the same as the last time Update() was called. To have a filter always to produce its largest possible region, users should call UpdateLargestPossibleRegion() instead.

Reimplemented from itk::ProcessObject.

◆ UpdateLargestPossibleRegion()

template<typename TInputImage>
void itk::ImageSink< TInputImage >::UpdateLargestPossibleRegion ( )
overridevirtual

Sets the output requested region to the largest possible region and updates.

This is the method users should call if they want the entire dataset to be processed. If a user wants to update the same output region as a previous call to Update() or a previous call to UpdateLargestPossibleRegion(), then they should call the method Update().

Reimplemented from itk::ProcessObject.

◆ VerifyInputInformation()

template<typename TInputImage>
void itk::ImageSink< TInputImage >::VerifyInputInformation ( ) const
overrideprotectedvirtual

Verifies that the inputs meta-data is consistent and valid for continued execution of the pipeline, throws an exception if not valid.

This method is called immediately before GenerateOutputInformation().

The ProcessObject implementation does nothing. Subclasses might check if all the inputs are in the same coordinate frame.

Reimplemented from itk::ProcessObject.
