If there is no AddSeed, you will need to add it to the ConnectedThreshold code, but I believe it has it.  I added AddSeed to the ConfidenceComnected and FuzzyConnectedness Code.

In the top right corner of the three views (axial, coronal and sagittal views), the indices I, J, K are explicitly shown as numerical values, on the bottom right the spatial positions of the mouse location are also shown. You can use this method to check if you are inputting the correct index values. 3D slicer is built from Itk and Vtk and is open source and freely available at www.slicer.org. I use this to select my seeds indices which I then input into my ITK code using the hard coded method that you use. (my itk code reads the indices from a file, actually)

>>> I use ITK read series of dicom data to segment by region growing.The result is not very good.So many regions cannot be deleted.So I want to set more indexes.I simply set series seed index like following:
>>>       InternalImageType::IndexType index,index1,index2;
>>>       index[0]=146;
>>>   index[1]=69;
>>>   index[2]=30;
>>>   index1[0]=60;
>>>   index1[1]=133;
>>>   index1[2]=40;
>>>   index2[0]=76;
>>>   index2[1]=194;
>>> index2[2]=50;
>>>       connectedThreshold->SetSeed(index);
>>>   connectedThreshold->SetSeed(index1);
>>>   connectedThreshold->SetSeed(index2);
>>> Then I get the result(series of dicom data).But all the images are black that just like nothing paiting on it.
