Dear Lee,<br>if you are really facing a memory issue one of the alternatives would be to downsample the input image.<br><br>The itk::ResmapleImageFilter will help you in this task.<br clear="all"><br>But before opting for this, you may want to go step by step and try to catch any exceptions you get.<br>
<br>There may well be other options.<br><br>
On the other hand, converting images to .vtk is not a required step for image processing purposes; you should be able to complete the entire image processing process within ITK. VTK is a useful and powerful tool used mainly for visualization purposes.<br>

<br><div>Hello, I have been trying to use RegionGrowingSegmentation to perform region growing segmentation on some 3D Dicom images. I was able to succeed on a small series of Dicom images by first transforming the DICOM series to a .vtk file using DicomSeriesReadWrite2.exe. However, on a full series of DICOM images, RegionGrowingSegmentation crashes with a memory error. (or at least I think I see a memory error appear in the console right before it dies).</div>
<div><br></div><div>Any ideas on how to overcome this? I have been poking through the code to see if I can allocate more memory somewhere, but I can't find anything like that.</div><div><br></div><div>Thanks in advance,</div>
