Detailed Description

template<class TInputImage, class TKernelImage = TInputImage, class TOutputImage = TInputImage, class TInternalPrecision = double>
class itk::FFTConvolutionImageFilter< TInputImage, TKernelImage, TOutputImage, TInternalPrecision >

Convolve a given image with an arbitrary image kernel using multiplication in the Fourier domain.

This filter produces output equivalent to the output of the ConvolutionImageFilter. However, it takes advantage of the convolution theorem to accelerate the convolution computation when the kernel is large.

Warning
This filter ignores the spacing, origin, and orientation of the kernel image and treats them as identical to those in the input image.

This code was adapted from the Insight Journal contribution:

protectedvirtual

FFTConvolutionImageFilter needs the entire image kernel, which in general is going to be a different size than the output requested region. As such, this filter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

InputSizeType itk::FFTConvolutionImageFilter< TInputImage, TKernelImage, TOutputImage, TInternalPrecision >::GetPadLowerBound ( ) const
protected

Get the lower bound for the padding of both the kernel and input images. Assuming that the regions of the kernel and input are the same, then this lower bound can be used to move the index of the padded kernel and padded input so that they are the same. This is important to avoid exceptions in filters that operate on these images.
