Thank you very much!I just mend my codes,replace the setseed to addseed .I always used dicomread from matlab to select my seed index.Maybe my seed index is not accurate.I will try 3D slicer.Sounds like a very good software.

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)
