Additional notes: - `itk::FFTConvolutionImageFilter` uses `itk::RealToHalfHermitianForwardFFTImageFilter` and `itk::HalfHermitianToRealInverseFFTImageFilter`, so it makes sense to focus on those first - forward FFT enlarges the requested output region to the largest possible region...

> This might not be due to performance improvement. It might be how the filter works. I think it needs the entire domain as it is equivalent to convolution with...

I see both of your points, this may be a snag in potential application to multiresolution speedup. Will experiment a bit with the region of interest filter to see how...

I have added a proof of concept notebook at [https://github.com/InsightSoftwareConsortium/ITKVkFFTBackend/pull/47](https://github.com/InsightSoftwareConsortium/ITKVkFFTBackend/pull/47) demonstrating how we can use subregions in FFTs for convolution speedup. @dzenanz @SimonRit would you please take a look and...

As a quick update, I am now actively working to apply the approved procedure in the notebook I linked above to `itk::FFTConvolutionImageFilter` to leverage the ITK pipeline for speedup over...

Starting to see improved results where FFT convolution time decreases as subregion size decreases. However, multithreaded spatial convolution still narrowly beats out FFT convolution for centered subregions. Will need to...

Hi @jhlegarreta, I won't be able to help this week but can take a look in the not-too-far future. I am not very familiar with the DCMTK CMake code in...

@jhlegarreta I was not able to immediately recreate this issue. The `ITKIODCMTKTestDriver` target appears to compile on first try on my Windows machine. I have double checked that `Module_ITKIODCMTK=ON` and...

@jhlegarreta I agree that this is a separate issue. The original error message ``` LINK : fatal error LNK1104: cannot open file 'ofstd.lib' ``` does not appear to be present...

@PranjalSahu If you have a moment, could you please confirm whether you see a similar autocomplete list for ITK Python on Linux?
