<div>i tautly agree with you, if there is no <span>good</span> tool i will implement it my self.</div>

<div>to save time, did you try 3D Slicer or Seg3d.</div>
<div>i found those tools while i was searching.</div>

<div id="yiv247350116yiv519929726"><font face="Helvetica, Arial, sans-serif">Hi there,<br>reading Dawood's mail I just realized that I (possibly we) forgot to make some little but important comments on the issue.<br><br>IMHO, there are (at least) three main difficulties when developping a segmentation method and/or using an already implemented segmentation method:<br><br>1. Good parametrization. A good selection of the parameters is crucial for the method.<br><br>2. The parameters' value is highly dependent on the image type and region to be segmented. Sometimes some compromise values work, but trial and error is usually necessary to find the appropriate range of values for your application.<br><br>3. Automatization of the method. Automating the segmentation process is by no means a trivial task; it may well happen that you are not able to achieve a fully automated method (in fact, automatic segmentation is a recurrent topic in medical image processing);
if the method
performs well, a minimal user interaction is then acceptable.<br><br><br>HTH.<br><br>Best regards,<br>JON HAITZ<br><br><br><br></font><br>El 08/11/2010 13:43, Dawood Masslawi escribiķ:
