Hi David,<br><br><br>The documentation of this filter suggest that a better implementation<br>is certainly possible:<br><br><br><quote><br>This filter uses some dodgy coding practices - most notably copying<br>the image data to a linear buffer to allow direct implementation of the <br>
published algorithm. It should therefore be quite a good candidate to<br>carry out tests of itk iterator performance with randomish access patterns. <br></quote><br><br><br><br>If your purpose is to remove objects that are smaller than a certain size<br>
(in number of pixels inside the object), you could achieve this by using<br>the sequence of filters:<br><br><ul><li>itkConnectedComponentImageFilter</li><li>itkRelabelComponentImageFilter</li></ul><br>and calling in the second one, the method:<br>
<br> SetMinimumObjectSize()<br><br><br>This should work in N-dimensions.<br><br><br>Regards,<br><br><br> Luis<br><br><br><br>---------------------------------------------------------------------------------------------<br>
