Hi Elhadj,<br><br>1) You can compute connected components with<br> the filter:<br><br><a href="http://www.itk.org/Doxygen/html/classitk_1_1ConnectedComponentImageFilter.html">http://www.itk.org/Doxygen/html/classitk_1_1ConnectedComponentImageFilter.html</a><br>
<br> this filter will produce an output where the <br> elements are labeled with integer numbers.<br> (but those numbers are not contiguous)<br><br>2) You could relabel the output of (1) by using<br> the filter:<br>
<br><a href="http://www.itk.org/Doxygen/html/classitk_1_1RelabelComponentImageFilter.html">http://www.itk.org/Doxygen/html/classitk_1_1RelabelComponentImageFilter.html</a><br><br><br>3) I'm not aware of a convex hull computation<br>
in ITK. However, if you don't need the convex<br> hull to be exact, you could get a similar result<br> by using the filter:<br><br><a href="http://www.itk.org/Doxygen/html/classitk_1_1VotingBinaryIterativeHoleFillingImageFilter.html">http://www.itk.org/Doxygen/html/classitk_1_1VotingBinaryIterativeHoleFillingImageFilter.html</a><br>

Is there an itk object, slicer module ... that can help to do this ?<br>Thanks, <br>
