<br>I guess you didnt change "int itkConnectedComponentImageFilterTest(int argc, char* argv[] )" to "int main( int argc, char* argv[])".....<div><br></div><div>thats a testing codes...you need to make a few changes before u run them....</div>

Hi, firstly, thank you for your reply.<br><br>I'm trying to run the code you suggested me to understand how it works but I find a problem that I've never had and that it a little strange in my opinion.<br>This is the error that I have:<br>
<br>/usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o: In function `_start':<br>/build/buildd/eglibc-2.10.1/csu/../sysdeps/i386/elf/start.S:115: undefined reference to `main'<br>collect2: ld returned 1 exit status<br>
<br>What does it mean?<br>Could you help me?<br>Thanks<br><font color="#888888">Daniela<br></font><div><br><br><br><hr>From: <a href="mailto:arpit392@gmail.com">arpit392@gmail.com</a><br>Date: Thu, 26 Aug 2010 13:23:16 +0530<br>

Hi everyone,<br>I need your help.<br><br>I have to implement a code with similar function to Matlab bwlabeln; Matlab's routine <code>L = bwlabeln(BW)</code> returns a label matrix <code>L</code> containing labels for the connected components in <code>BW</code>; the elements of <code>L</code> are integer values greater than or equal to 0. The pixels labeled 0 are the background.<br>
<br>I looked for similar itk method in itk User's Guide but I didn't find anything... could anyone help me?<br><br>Thanks of all,<br>Daniela<br> </div>
