Detailed Description

template<class TInputImage, class TGradientImage = TInputImage, class TOutputImage = TInputImage>
class itk::RobustAutomaticThresholdImageFilter< TInputImage, TGradientImage, TOutputImage >

Threshold an image using robust automatic threshold selection (RATS) method.

RobustAutomaticThresholdImageFilter takes two inputs: the image to be thresholded and a image of gradient magnitude of that image. The threshold is computed as the mean of the pixel values in the input image weighted by the pixel values in the gradient image. The threshold computed that way should be the mean pixel value where the intensity change the most.

virtual::itk::LightObject::Pointer itk::RobustAutomaticThresholdImageFilter< TInputImage, TGradientImage, TOutputImage >::CreateAnother ( void  ) 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 TGradientImage = TInputImage, class TOutputImage = TInputImage>
void itk::RobustAutomaticThresholdImageFilter< TInputImage, TGradientImage, TOutputImage >::GenerateData ( ) [protected, virtual]

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead.

Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage , class TGradientImage = TInputImage, class TOutputImage = TInputImage>
void itk::RobustAutomaticThresholdImageFilter< TInputImage, TGradientImage, TOutputImage >::GenerateInputRequestedRegion ( ) [protected, virtual]

What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierachy. Up till now, the base assumption has been that the largest possible region will be requested of the input.

This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types.

template<class TInputImage , class TGradientImage = TInputImage, class TOutputImage = TInputImage>
void itk::RobustAutomaticThresholdImageFilter< TInputImage, TGradientImage, TOutputImage >::operator= ( const Self ) [private]

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.
