Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::ZeroCrossingImageFilter< TInputImage, TOutputImage >

This filter finds the closest pixel to the zero-crossings (sign changes) in a signed itk::Image.

Pixels closest to zero-crossings are labeled with a foreground value. All other pixels are marked with a background value. The algorithm works by detecting differences in sign among neighbors using city-block style connectivity (4-neighbors in 2d, 6-neighbors in 3d, etc.).

Inputs and Outputs
The input to this filter is an itk::Image of arbitrary dimension. The algorithm assumes a signed data type (zero-crossings are not defined for unsigned data types), and requires that operator>, operator<, operator==, and operator!= are defined.
The output of the filter is a binary, labeled image of user-specified type. By default, zero-crossing pixels are labeled with a default "foreground" value of itk::NumericTraits<OutputDataType>::OneValue(), where OutputDataType is the data type of the output image. All other pixels are labeled with a default "background" value of itk::NumericTraits<OutputDataType>::ZeroValue().
Parameters
There are two parameters for this filter. ForegroundValue is the value that marks zero-crossing pixels. The BackgroundValue is the value given to all other pixels.

template<typename TInputImage, typename TOutputImage>
virtual::itk::LightObject::Pointer itk::ZeroCrossingImageFilter< 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<typename TInputImage, typename TOutputImage>
virtual void itk::ZeroCrossingImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )
overridevirtual

ZeroCrossingImageFilter needs a larger input requested region than the output requested region (larger by the kernel size to do comparisons between the central pixel and ite neighbors). Thus ZeroCrossingImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

void itk::ZeroCrossingImageFilter< TInputImage, TOutputImage >::ThreadedGenerateData ( const OutputImageRegionType outputRegionForThread,

overrideprotectedvirtual

ZeroCrossingImageFilter can be implemented as a multithreaded filter. Therefore,this implementation provides a ThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling ThreadedGenerateData(). ThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread"
