Hi<div><br></div><div>I'm not too sure if those filters are what I need since I'm trying to get the user to select seed points on any black holes he sees and I dont see any 'addSeed'</div><div>mechanism for those filters.</div>
<div><br></div><div>In the examples, there is:</div><div> filter->SetRadius( indexRadius )</div><div><br></div><div>would that be a seed point from the image?</div><div>Or does this filter look at the whole image and finds black wholes to get rid of?</div>
