[Insight-users] Using MultiResolutionPyramidImageFilter :

[Tamas Ungi]

Dear All,

I have encountered the same problem with MultiResolutionPyramid, could
anyone help me?

No output is generated by the writer.

 

The code is:

 

  typedef itk::Image< unsigned char, 2 > Image;

  typedef itk::ImageFileReader< Image > Reader;

  typedef itk::ImageFileWriter< Image > Writer;

  

  // read image

  Reader::Pointer reader = Reader::New();

  reader->SetFileName( argv[1] );

  reader->Update();

  Image::Pointer image = reader->GetOutput();

  image->Print( std::cout );

 

  // construct a pyramid

  typedef itk::MultiResolutionPyramidImageFilter< Image, Image > Pyramid;

  Pyramid::Pointer pyramid = Pyramid::New();

  pyramid->SetNumberOfLevels( 3 );

  pyramid->SetInput( reader->GetOutput() );

  pyramid->Print( std::cout );

  pyramid->Update();

  

  // write pyramid

  Writer::Pointer writer = Writer::New();

  writer->SetFileName( "out.bmp" );

  writer->SetInput( pyramid->GetOutput( 1 ) );

  writer->Update();

  

Output is:
