Detailed Description

template<class TInputImage, class TOutputImage = TInputImage>
class itk::ShotNoiseImageFilter< TInputImage, TOutputImage >

Alter an image with shot noise.

The shot noise follows a Poisson distribution:

$ I = N(I_0) $
where $ N(I_0) $ is a Poisson-distributed random variable of mean $ I_0 $. The noise is thus dependent on the pixel intensities in the image.

The intensities in the image can be scaled by a user provided value to map pixel values to the actual number of particles. The scaling can be seen as the inverse of the gain used during the acquisition. The noisy signal is then scaled back to its input intensity range:

$ I = \frac{N(I_0 \times s)}{s} $
where $ s $ is the scale factor.

The Poisson-distributed variable $ \lambda $ is computed by using the algorithm:

$ \begin{array}{l} k \leftarrow 0 \\ p \leftarrow 1 \\ \textbf{repeat} \\ \left\{ \begin{array}{l} k \leftarrow k+1 \\ p \leftarrow p \ast U() \end{array} \right. \\ \textbf{until } p > e^{\lambda} \\ \textbf{return} (k) \end{array} $
where $ U() $ provides a uniformly distributed random variable in the interval $ [0,1] $.

This algorithm is very inefficient for large values of $ \lambda $, though. Fortunately, the Poisson distribution can be accurately approximated by a Gaussian distribution of mean and variance $ \lambda $ when $ \lambda $ is large enough. In this implementation, this value is considered to be 50. This leads to the faster algorithm:

$ \lambda + \sqrt{\lambda} \times N()$
where $ N() $ is a normally distributed random variable of mean 0 and variance 1.

virtual::itk::LightObject::Pointer itk::ShotNoiseImageFilter< TInputImage, TOutputImage >::CreateAnother ( ) 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.

Reimplemented from itk::Object.

template<class TInputImage , class TOutputImage = TInputImage>
void itk::ShotNoiseImageFilter< TInputImage, TOutputImage >::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.
