Hello.
When I try to use image reading functionality inside .cu file, I get compilation errors, whereas if I put the same code inside .cpp file, which is compiler using regular host compiler, the code normally compiles.
Platform:
I get the following errors:
C:\.conan\79dfc2\1\include\ITK-5.3\itkImageBase.h(117): error C2555: 'itk::ImageBase<3>::CreateAnother': overriding virtual function return type differs and is not covariant from 'itk::Object::CreateAnother'

I am not sure what subset of ITK can be used within CUDA code, but probably only GPU-related classes. @simon.rit @LucasGandel do have a more detailed answer?

I have never managed to use ITK in cu files when I tried a few years ago. This is why RTK separates the Cuda code completely from ITK. See for example

Only the cu files are compiled with nvcc. But RTK is quite old now and we sticked to this approach. Things might have changed since…

hi，I got the same error when compiling the following code, have you came out any solution to use itk in .cu file?
#include<iostream>
using namespace std;
#include<cuda_runtime.h>
#include<itkImage.h>
#include<itkNiftiImageIO.h>
#include<itkImageFileReader.h>
#include<itkImageFileWriter.h>
const int Dimension = 3;
using PixelType = short;
using ImageType = itk::Image<PixelType, Dimension>;
const int BPLINE_BOARD_SIZE = 3;
int main()
{
ImageType::Pointer image;
return 0;
}

I split the code into .cpp and .cu file, read the image in the .cpp and passed the raw buffer pointer to .cu via image->GetBufferPointer().
