I just got your class in my version of vtk and up and running in Java, and it's not working for me. I was wondering what I'm doing wrong, could you help me out?<div><br></div><div>Thanks</div><div><br></div><div><div>

Hi Jonathan,<div><br></div><div>I put my flood-fill filter on github, and tested it to make sure it</div><div>still works:</div><div><a href="http://github.com/dgobbi/VTK/tree/flood-fill/Imaging/" target="_blank">http://github.com/dgobbi/VTK/tree/flood-fill/Imaging/</a><br>
<br></div><div>The interface is just like the vtkThresholdFilter, except that it</div><div>has a method called SetSeedPoints() to allow you to set your</div><div>seeds. For a binary image, call ThresholdByUpper(1) so that</div>
<div>you can set seeds inside any non-zero islands that you want</div><div>to keep in your output.</div><div><br></div><div>I'll probably contribute this class to VTK after I have brought</div><div>it up-to-date (it was originally written for VTK 4).</div>

I have a binary vtkImageData class and I want to do 2 things with it, and I don't know how.<div><br></div><div>1. I want to remove all islands from the image except one. I want to identify the island not to be removed by a pixel location. I have seen vtkImageIslandRemoval2D, and I don't think that'll work for me, because I do not know anything about the island's size that I want to keep (it could be big, small, or in the middle), all that I know is one point which is guaranteed to be interior to one island, and that's the island I want to keep.</div>
<div><br></div><div>2. I want to do hole filling on the output of step 1 and I don't know how to do that. I saw vtkFillHolesFilter but that appears only to work on poly data. I'd like something analogous to that for vtkImageData.</div>
<div><br></div><div>If anyone knows how to do these things, I'd appreciate it. Also, if it matters, I'm coding in Java.</div><div><br></div><div>Thanks</div>
