ARB Prototype Code

Gaussian Blur

  • Open an image
  • Filter the image with a Gaussian blur using sigma = 2
  • Write the image back out

Option 1 - Fully procedural

// Read the image
itk::simple::ImageFileReader reader;
itk::simple::Image::Pointer im = reader.execute( "sample/path/to/image.jpg" );

// Apply Gaussian with sigma = 2
itk::simple::Gaussian filter;
im = filter.execute( im, 2 );

// Write out the image
itk::simple::ImageFileWriter writer;
writer.execute( im, "sample/path/to/output.png" );

Option 2 - Procedural with parameter setting

// Read the image
itk::simple::ImageFileReader reader;
reader.SetFilename( "sample/path/to/image.jpg" );
itk::simple::Image::Pointer im = reader.execute();

// Apply Gaussian with sigma = 2
itk::simple::Gaussian filter;
filter.SetSigma( 2 );
im = filter.execute( im );

// Write out the image
itk::simple::ImageFileWriter writer;
writer.SetFilename( "sample/path/to/output.png" );
writer.execute( im );

Option 3 - Pipelined

// Read the image
itk::simple::ImageFileReader reader;
reader.SetFilename( "sample/path/to/image.jpg" );

// Apply Gaussian with sigma = 2
itk::simple::Gaussian filter;
filter.SetSigma( 2 );
filter.SetInput( reader.getOutput() );

// Write out the image
itk::simple::ImageFileWriter writer;
writer.SetFilename( "sample/path/to/output.png" );
writer.SetInput( filter->GetOutput() );

// Update the pipieline
writer.Update();
