<br>Hi Yusuf,<br><br>You can convert the pixel type of the Watershed output<br>by using the filter:<br><br>               RelabelComponentImageFilter<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>
