C++ SEGFULT后返回0；

我想使用ITK的一个简单的颜色比例程序，但我得到一个segfault后返回0；主要功能的定义。 这是我的密码

#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkImageFileWriter.h"
#include <iostream>
#include <string>
#include <vector>
#include "itkRGBPixel.h"


const unsigned int  Dimension = 2;
typedef itk::RGBPixel< unsigned char >       PixelType;
typedef itk::Image< PixelType, Dimension >   ImageType;
typedef itk::ImageFileReader< ImageType >    ReaderType;
typedef itk::ImageFileWriter< ImageType >   WriterType;

int main(int argc, char** argv)
{   
std::string input=argv[1], output=argv[2];

//allocation of the image data
ReaderType::Pointer reader    = ReaderType::New();
WriterType::Pointer writer = WriterType::New();

reader->SetFileName(input);
writer->SetFileName(output);

reader->Update(); 

//access image
ImageType::Pointer image = reader->GetOutput();
ImageType::Pointer output_img;

 //apparently providing the spacing and origin in ITK is mandatory
ImageType::SpacingType spacing;
spacing[0] = 0.33;
spacing[1] = 0.33;
image->SetSpacing(spacing);

ImageType::PointType origin;
origin[0] = 0.0;
origin[1] = 0.0;
image->SetOrigin(origin);

writer->SetInput( reader->GetOutput() ); 
    writer->Update(); 

 return EXIT_SUCCESS;
}

即使有36000个无用的try/catch语句，我仍然会在main之后遇到相同的分段错误

有人能帮我吗

提前感谢您

此代码适用于我：

#include <string>
#include <vector>

#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkImageFileWriter.h"
#include "itkRGBPixel.h"

int main(int argc, char** argv)
{
  std::string input = "/home/doriad/temp/test.png";
  std::string output= "output.png";

  const unsigned int  Dimension = 2;
  typedef itk::RGBPixel< unsigned char >       PixelType;
  typedef itk::Image< PixelType, Dimension >   ImageType;
  typedef itk::ImageFileReader< ImageType >    ReaderType;
  typedef itk::ImageFileWriter< ImageType >   WriterType;

  //allocation of the reader
  ReaderType::Pointer reader    = ReaderType::New();
  reader->SetFileName(input);
  reader->Update();

  //access image
  ImageType::Pointer image = reader->GetOutput();
//  ImageType::Pointer output_img;// This line does nothing

  //apparently providing the spacing and origin in ITK is mandatory
  // The spacing and origin are read from the file.
//  ImageType::SpacingType spacing;
//  spacing[0] = 0.33;
//  spacing[1] = 0.33;
//  image->SetSpacing(spacing);

//  ImageType::PointType origin;
//  origin[0] = 0.0;
//  origin[1] = 0.0;
//  image->SetOrigin(origin);

  WriterType::Pointer writer = WriterType::New();
  writer->SetFileName(output);
  writer->SetInput( reader->GetOutput() );
  writer->Update();

 return EXIT_SUCCESS;
}

当然，您必须将“输入”字符串更改为您实际拥有的文件。

看起来您正在破坏堆栈。您可以发布一条消息吗？另外，您不应该使用

-1

从

main

返回。任何非零数字通常都会被视为错误，如果您想确定，请返回。谢谢您的回复。我已将代码编辑为SSCCE格式。它足够简短、独立，并且可以编译。基本上，它是从一个文件中读取一个图像，然后直接在另一个文件中重写它。（我所知道的）没有别的。问题仍然存在。顺便说一句，这张图片是png图片。我正在使用Itk库！除非提供完整的构建，或者复制粘贴库的每个头文件/源文件的全部内容，否则就不可能生成sscce！好的，谢谢。我猜这个错误来自setspace或setOrigin。如果仅将itk用于非医学图像处理，为什么必须使用它？无论如何，谢谢你的帮助。问题已解决。如果您的文件没有其他说明（即，如果您阅读非医疗文件（如正常png），读者将生成您期望的间距（1）和原点（0）。您已通过接受答案正确地结束了问题。
