What I tried was giving the initial segmented data as the output of the level-set filter (for instance instead of giving FastMarchingFilter->GetOutput(), I gave reader->GetOutput, after reading the data) . But it didn't work. How can I do this??</div><div><br></div><div>Sincerely thank you in advance!</div><div><br></div><div>Regards,</div><div>Abayiz <br></div></div></body></html>
