Detailed Description

template<typename TInputImage, typename TKernelImage = TInputImage, typename TOutputImage = TInputImage, typename 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:

"FFT Based Convolution" by Gaetan Lehmann https://doi.org/10.54294/0iky0u

InternalSizeType itk::FFTConvolutionImageFilter< TInputImage, TKernelImage, TOutputImage, TInternalPrecision >::GetFFTPadSize ( ) const

protected

Get padding around the region of interest that results from FFT factoring requirements. FFT typically requires that image side lengths are factorable only by a fixed set of prime numbers (often 2, 3, and 5). After the input image is padded for the kernel width and cropped to the region of interest the result is then padded for FFT execution. This value is reused for kernel padding and output cropping.
