Detailed Description

template<typename TInputImage, bool doDilate, typename TOutputImage = TInputImage>
class itk::ParabolicErodeDilateImageFilter< TInputImage, doDilate, TOutputImage >

Parent class for morphological operations with parabolic structuring elements.

Parabolic structuring elements are the morphological counterpart of the gaussian function in linear processing. Parabolic structuring elements are dimensionally decomposable and fast algorithms are available for computing erosions and dilations along lines. This class implements the "point of contact" algorithm, which is reasonably efficient. Improved versions, that are nearly independent of structuring function size, are also known but haven't been implemented here.

Parabolic structuring functions can be used as a fast alternative to the "rolling ball" structuring element classically used in background estimation, for example in ImageJ, have applications in image sharpening and distance transform computation.

This class uses an internal buffer of RealType pixels for each line. This line is cast to the output pixel type when written back to the output image. Since the filter uses dimensional decomposition this approach could result in inaccuracy as pixels are cast back and forth between low and high precision types. Use a high precision output type and cast manually if this is a problem.

This filter is threaded. Threading mechanism derived from SignedMaurerDistanceMap extensions by Gaetan Lehman
