Detailed Description

template<class TImage>
class itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >

Fills in holes and cavities by iteratively applying a voting operation.

This filter uses internally the VotingBinaryHoleFillingImageFilter, and runs it iteratively until no pixels are being changed or until it reaches the maximum number of iterations. The purpose of the filter is to fill in holes of medium size (tens of pixels in radius). In principle the number of iterations is related to the size of the holes to be filled in. The larger the holes, the more iteration must be run with this filter in order to fill in the full hole. The size of the neighborhood is also related to the curvature of the hole borders and therefore the hole size. Note that as a colateral effect this filter may also fill in cavities in the external side of structures.

This filter is templated over a single image type because the output image type must be the same as the input image type. This is required in order to make the iterations possible, since the output image of one iteration is taken as the input image for the next iteration.

Member Function Documentation

template<class TImage >
virtual::itk::LightObject::Pointer itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::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 TImage >
void itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GenerateData ( ) [protected, virtual]
template<class TImage >
virtual const InputPixelType& itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetBackgroundValue ( ) [virtual]

Get the value associated with the Foreground (or the object) on the binary input image and the Background .

template<class TImage >
virtual const unsigned int& itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetCurrentNumberOfIterations ( ) [virtual]

Number of iterations executed at any given time. This is useful at the end of the execution in order to verify how many iterations were performed.

template<class TImage >
virtual const InputPixelType& itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetForegroundValue ( ) [virtual]

Get the value associated with the Foreground (or the object) on the binary input image and the Background .

template<class TImage >
virtual const unsigned int& itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetMajorityThreshold ( ) [virtual]

Majority threshold. It is the number of pixels over 50% that will decide whether an OFF pixel will become ON or not. For example, if the neighborhood of a pixel has 124 pixels (excluding itself), the 50% will be 62, and if you set upd a Majority threshold of 5, that means that the filter will require 67 or more neighbor pixels to be ON in order to switch the current OFF pixel to ON. The default value is 1.

template<class TImage >
virtual const unsigned int& itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetMaximumNumberOfIterations ( ) [virtual]

Maximum number of iterations. This filter is executed iteratively as long as at least one pixel has changed in a previous iteration, or until the maximum number of iterations has been reached.

template<class TImage >
virtual const char* itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::ImageToImageFilter< TImage, TImage >.

template<class TImage >
virtual const unsigned int& itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetNumberOfPixelsChanged ( ) [virtual]

Returns the number of pixels that changed when the filter was executed.

template<class TImage >
virtual const InputSizeType& itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::GetRadius ( ) [virtual]

Get the radius of the neighborhood used to compute the median

template<class TImage >
static Pointer itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<class TImage >
void itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::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.

Reimplemented from itk::ImageToImageFilter< TImage, TImage >.

template<class TImage >
virtual void itk::VotingBinaryIterativeHoleFillingImageFilter< TImage >::SetCurrentNumberOfIterations ( unsigned int  _arg) [virtual]
