<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Thanks Sergio, I have the BinaryContourImageFilter working. I also got the SimpleContourExtractorImageFilter to work by increasing the radius. I have one more related question. I used:<div><br></div><blockquote type="cite"><div><div>contour->SetFullyConnected(false); // true makes thicker contours</div></div></blockquote><div><br></div><div>to get a thinner contour, but it still appears very thick. Is there any way to get closer to a 1-pixel wide contour from a 3D binary image?</div><div><br></div><div>Thanks,</div><div><br></div><div>Sara </div><div><br></div><div><br><div><div><div>On Oct 8, 2010, at 12:19 AM, Sergio Vera wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Hi Sara<div><br></div><div>As far as I know, SimpleContourExtractorImageFilter works OK in 3d images.
