</SPAN>I have a sequence of human body images which comes from a Chinese
Virtual Human Project.( one of them is shown below). I want to segment organs
such as gray matter from this image sequence using ITK. But since I have not
enough segmentation experience using ITK, I'd like to ask for some suggestions
about segmentation methods using ITK. Any suggestion is
grateful.<o:p></o:p></FONT></FONT></SPAN></P>

</SPAN>In my present plan, I want to use the ITK framework to integrate
several segmentation methods within ITK to form a hybrid segmentation method. Is
my plan feasible? Are there any recommended
methods?<o:p></o:p></FONT></FONT></SPAN></P>
