[Insight-users] managed itkConfidenceConnectedImageFilter Question

[Dan Mueller]

Hi Ali,

Try the following code snippet:

    // Read input
    itkImageBase input = itkImage_UC3.New();
    itkImageBase output = itkImage_UC3.New();
    itkImageFileReader reader = itkImageFileReader.New(input);
    reader.FileName = "C:/Temp/input.mha";
    reader.Update();
    reader.GetOutput(input);
    input.DisconnectPipeline();

    // Create seed
    itkSize size = input.BufferedRegion.Size;
    itkIndex start = input.BufferedRegion.Index;
    itkIndex seed = new itkIndex(input.Dimension);
    for (int i=0; i<input.Dimension; i++) {
        seed[i] = start[i] + size[i] / 2;
    }

    // Run filter
    itkConfidenceConnectedImageFilter filter =
        itkConfidenceConnectedImageFilter.New(input, output);
    filter.SetInput(input);
    filter.AddSeed(seed);
    filter.InitialNeighborhoodRadius = 2U;
    filter.ReplaceValue = 128;
    filter.Update();
    filter.GetOutput(output);
    output.DisconnectPipeline();

    // Write output
    output.Write("C:/Temp/output.mha");

    // Clean up
    input.Dispose();
    output.Dispose();
    filter.Dispose();

HTH

Cheers, Dan
