<p>Hi Dzenan,</p>
<p><br>
</p>
<p>My goal is to obtain the big contour of the 3D image. For this reason, I tried to use
<span style="font-family: Calibri, sans-serif; font-size: 14.6667px;">Binary Fill hole Image Filter and after the <span>BinaryContourImageFilter.</span></span></p>
<p><span style="font-family: Calibri, sans-serif; font-size: 14.6667px;"><span>Could you provide me another way using ITK, please?</span></span></p>

your image does not have any holes! The input and output images are binary identical (examined using file compare tool). If I modify your input image to also contain a real hole (not connected to image edge or the background), it gets filled properly. See attached.</div>
