<br>
I have a black and white image, that has one black connected region. Is<br>
there a way to extract the black connected region and have it as polydata?<br>
I want to visualize this region as polydata and work with its geometry<br>
without the image data.<br>
<br>
I am kind of not experienced with VTK and this might be a simple question.<br>
<br>
Thanks.<br>
