What PixelType are you using? Your PixelType must be char (1 byte). '0 as bg and 1 as fg' will work (without specifying the DilateValue) only if your PixelType is 1 bit long.<br><br>Saurabh<br><br><div class="gmail_quote">

Hi Saurabh,<div><br></div><div>I can use SetDilateValue or I must use it ? </div><div>
Because I saw this information but I assume that by default all pixel >0 are treated like one. And in the wiki (<a href="http://www.itk.org/Wiki/ITK/Examples/Morphology/BinaryDilateImageFilter" target="_blank">http://www.itk.org/Wiki/ITK/Examples/Morphology/BinaryDilateImageFilter</a>) they don't use SetDilateValue because the image is binary.</div>
