以下是使用 Reconstruction Toolkit 去伪影的 C++ 代码示例:
```c++
#include <iostream>
#include <string>
#include <vector>
#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkImageFileWriter.h"
#include "itkSinusoidalUnwrapper.h"
int main(int argc, char* argv[])
{
// Check the input arguments
if (argc < 3)
{
std::cerr << "Usage: " << argv[0] << " <inputImage> <outputImage>" << std::endl;
return EXIT_FAILURE;
}
// Define the pixel type and dimension of the image
constexpr unsigned int Dimension = 2;
using PixelType = float;
using ImageType = itk::Image<PixelType, Dimension>;
// Define the reader and writer types
using ReaderType = itk::ImageFileReader<ImageType>;
using WriterType = itk::ImageFileWriter<ImageType>;
// Read the input image
auto reader = ReaderType::New();
reader->SetFileName(argv[1]);
try
{
reader->Update();
}
catch (itk::ExceptionObject& error)
{
std::cerr << "Error reading input image: " << error << std::endl;
return EXIT_FAILURE;
}
auto inputImage = reader->GetOutput();
// Define the unwrapper type
using UnwrapperType = itk::SinusoidalUnwrapper<ImageType, ImageType>;
auto unwrapper = UnwrapperType::New();
unwrapper->SetInput(inputImage);
// Perform the phase unwrapping
try
{
unwrapper->Update();
}
catch (itk::ExceptionObject& error)
{
std::cerr << "Error performing phase unwrapping: " << error << std::endl;
return EXIT_FAILURE;
}
// Write the output image
auto writer = WriterType::New();
writer->SetFileName(argv[2]);
writer->SetInput(unwrapper->GetOutput());
try
{
writer->Update();
}
catch (itk::ExceptionObject& error)
{
std::cerr << "Error writing output image: " << error << std::endl;
return EXIT_FAILURE;
}
return EXIT_SUCCESS;
}
```
此代码演示了如何使用 Reconstruction Toolkit 中的 `itk::SinusoidalUnwrapper` 类来去除伪影。首先,代码读取输入图像,并将其作为输入传递给 `itk::SinusoidalUnwrapper` 类。然后,代码调用 `Update()` 方法执行相位展开。最后,代码将相位展开后的图像写入输出文件。
