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 and the "intersection" algorithm. The contact point algorithm is faster at small scales. The intersection algorithm was rediscovered by Felzenszwalb & Huttenlocher, but was actually described and tested by van den Boomgaard many years earlier. The intersection algorithm is faster for scales > 1, and independent of scale. It also seems to perform significantly better in the distance transform application. The intersection algorithm is also used in the IJ article on generalised distance transforms.
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.
