Detailed Description

template<typename TInputImage, typename TOutputImage, typename TAccumulator>
class itk::ProjectionImageFilter< TInputImage, TOutputImage, TAccumulator >

Implements an accumulation of an image along a selected direction.

This class accumulates an image along a dimension and reduces the size of this dimension to 1. The dimension being accumulated is set by ProjectionDimension.

Each pixel is the cumulative sum of the pixels along the collapsed dimension and reduces the size of the accumulated dimension to 1 (only on the accumulated).

The dimensions of the InputImage and the OutputImage are either the same or dimension of OutputImage is dimension of InputImage minus one. In the latter case, the direction cosine of the output image is set to the identity.

This class is parameterized over the type of the input image and the type of the output image.

This class was contributed to the Insight Journal by Emiliano Beronich and Gaetan Lehmann. The original paper can be found at https://doi.org/10.54294/0pjyho

◆ DynamicThreadedGenerateData()

template<typename TInputImage, typename TOutputImage, typename TAccumulator>

void itk::ProjectionImageFilter< TInputImage, TOutputImage, TAccumulator >::DynamicThreadedGenerateData ( const OutputImageRegionType & outputRegionForThread )

overrideprotectedvirtual

If an imaging filter can be implemented as a multithreaded algorithm, the filter will provide an implementation of ThreadedGenerateData() or DynamicThreadedGenerateData(). This superclass will automatically split the output image into a number of pieces, spawn multiple threads, and call (Dynamic)ThreadedGenerateData() in each thread. Prior to spawning threads, the BeforeThreadedGenerateData() method is called. After all the threads have completed, the AfterThreadedGenerateData() method is called. If an image processing filter cannot support threading, that filter should provide an implementation of the GenerateData() method instead of providing an implementation of (Dynamic)ThreadedGenerateData(). If a filter provides a GenerateData() method as its implementation, then the filter is responsible for allocating the output data. If a filter provides a (Dynamic)ThreadedGenerateData() method as its implementation, then the output memory will allocated automatically by this superclass. The (Dynamic)ThreadedGenerateData() method should only produce the output specified by "outputThreadRegion" parameter. (Dynamic)ThreadedGenerateData() cannot write to any other portion of the output image (as this is responsibility of a different thread).

DynamicThreadedGenerateData() is the newer variant without threadId, and is the preferred signature, which is called by default. This variant can split the requested region into different number of pieces depending on current multi-processing load, which allows better load balancing. The non-dynamic (also known as classic) ThreadedGenerateData() signature has threadId, and number of pieces to be split into is known in advance. It is activated by calling this->DynamicMultiThreadingOff(); in derived class constructor. It should be used when the multi-threaded algorithm needs to pre-allocate some data structure with size dependent on the number of pieces (also known as chunks, work units, and sometimes also incorrectly as threads). Only PlatformMultiThreader guarantees that each piece will be processed in its own specific thread. Pool and TBB multi-threaders maintain a pool of threads (normally equal to number of processing cores) which they use to process the pieces. This normally results in a single thread being reused to process multiple work units.
