ITK学习笔记——RGB图像读取写入

RGB图像读取写入属于ITK基本操作，比较简单，直接套用下面代码即可，由于ITK不支持可视化，所以需要将处理完后的图片写入文件中打开查看，所以只需要改下面代码中的输入输出路径即可。

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

int main(int argc, char ** argv)
{
	typedef itk::RGBPixel< unsigned char >   PixelType;
	typedef itk::Image< PixelType, 2 >       ImageType;

	typedef itk::ImageFileReader< ImageType >  ReaderType;
	typedef itk::ImageFileWriter< ImageType >  WriterType;
	ReaderType::Pointer reader = ReaderType::New();
	WriterType::Pointer writer = WriterType::New();

	const char * inputFilename = "C:/input/Lenna.jpeg";      //输入图片路径
	const char * outputFilename = "C:/output/Lenna.jpeg";    //输出图片路径

	reader->SetFileName(inputFilename);
	writer->SetFileName(outputFilename);

	ImageType::Pointer image = reader->GetOutput();
	writer->SetInput(image);

	writer->Update();

	return EXIT_SUCCESS;
}
