Hi Tao, I think you want the CastImageFilter <https://itk.org/Doxygen/html/classitk_1_1CastImageFilter.html> from ITK.
Something like this: using castToImageType = itk::CastImageFilter<itk:::Image<float,3>, itk::CudaImage<float,3>>; typename castToImageType::Pointer castfilter = castToImageType::New(); castfilter->SetInput(projectionReader->GetOutput()); castfilter->Update(); auto cuda_image = castfilter->GetOutput(); Best regards Andreas __________________________________ Andreas Gravgaard Andersen Department of Oncology, Aarhus University Hospital Nørrebrogade 44, 8000, Aarhus C Mail: agravga...@protonmail.com Cell: +45 3165 8140 On Wed, 16 Jan 2019 at 22:59, tao sun <colddie...@gmail.com> wrote: > Hi, > > I have read in some image using itk::ImportImageFilter. > ImportFilterType::Pointer projectionReader = ImportFilterType::New(); > ... > projectionReader->Update(); > > The type of the image is itk:::Image<float,3>.
