Detailed Description

template<class TInputImage, class TOutputImage>
class itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >

Label pixels that are connected to one seed but not another.

/class IsolatedConnectedImageFilter

IsolatedConnectedImageFilter labels pixels with ReplaceValue that are connected to Seed1 AND NOT connected to Seed2. The filter adjusts the upper threshold until the two seeds are not connected. The user supplies a Lower threshold. The algorithm uses a binary search to adjust the upper threshold, starting at the largest possible value for the InputImagePixelType.

Member Function Documentation

template<class TInputImage, class TOutputImage> void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion (  DataObject *    output )  [protected, virtual]

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region. Reimplemented from itk::ProcessObject.

template<class TInputImage, class TOutputImage> void itk::IsolatedConnectedImageFilter< TInputImage, 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. See also: ThreadedGenerateData() Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage, class TOutputImage> void itk::IsolatedConnectedImageFilter< TInputImage, 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 this 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. See also: ProcessObject::GenerateInputRequestedRegion(), ImageSource::GenerateInputRequestedRegion() Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> virtual const char* itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::GetClassName (    )  const [virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> virtual void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetLower (  InputImagePixelType    _arg )  [virtual]
