<div dir="auto">Thanks Matt! I was not aware of this filter. However, instead of masking an image after filtering, I would like that the filter itself ignores a specific region (i.e. background) for any calculation. Masking is not enough if I apply large sigmas. I am also interested in making the filter faster by ignoring computations in specified voxels.<div dir="auto"><br></div><div dir="auto">Best,</div><div dir="auto"><br></div><div dir="auto">Albert<br><div dir="auto"><br></div><div dir="auto"><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On May 1, 2017 17:22, "Matt McCormick" <<a href="mailto:matt.mccormick@kitware.com">matt.mccormick@kitware.com</a>> wrote:<br type="attribution"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Albert,<div><br></div><div>The result could be masked.
