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 not 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.

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.
