[Insight-users] Matlab bwlabeln in itk

[Daniela Sacchetto]

ok Arpit...I think that there is a problem because I can't run a code without the main (and the code that you suggested me doesn't have the main...) .
The problem is that I'm a starter in C++ and so, I don't understand how use that code. Usually I download file.h, I include them in my main program and everything runs perfectly. Now I have downloaded a file.cxx that starts as a main and so I'm not able to use it....

Sorry for my, maybe, stupid question...

Regards
Daniela

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

Hi, firstly, thank you for your reply.

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.
This is the error that I have:



/usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o: In function `_start':
/build/buildd/eglibc-2.10.1/csu/../sysdeps/i386/elf/start.S:115: undefined reference to `main'
collect2: ld returned 1 exit status



What does it mean?
Could you help me?
Thanks
Daniela

u can use itkConnectedComponentImageFilterTest.cxx, it performs a similar task...except it associates each label with a different colour, to help visualize the different parts using itkRelabelComponentImageFilter, you can comment this part to get your desired results...




Cheers,Arpit

Hi everyone,
I need your help.

I have to implement a code with similar function to Matlab bwlabeln; Matlab's routine L = bwlabeln(BW) returns a label matrix L containing labels for the connected components in BW; the elements of L are integer values greater than or equal to 0. The pixels labeled 0 are the background.





I looked for similar itk method in itk User's Guide but I didn't find anything... could anyone help me?

Thanks of all,
Daniela
