Hi again,<div><br></div><div>Ok, I've verified that using:</div><div><br></div><div><span class="Apple-style-span" style="font-size: 14px; background-color: rgb(255, 255, 255); "><table align="center" width="95%" border="0" cellspacing="0" cellpadding="0">

The holes I didn't want disappeared, the filter cleaned the segmented for me.<br>
<br>My current problem is now vtk is suddenly not showing the output of the above filter fro some reason.<br>First I segment with confidence connected and then I feed the output of confidence connected into the hole filling filter and when I go to see the output, its just a black screen. Partial code below, I have a display function elsewhere making using of the connector, the image type is constant throughout (signed short and 2D):<br>
