Sergio, thanks for your clarification.<br><br> I use ImageJ and, following your advise, I change the "Enhance Contrast" options, setting them to "Normalize"... now I can see the skeleton!<br><br>Regards<br>Daniela<br><br><hr id="stopSpelling">Date: Mon, 31 May 2010 10:01:00 +0200<br>Subject: Re: [Insight-users] Skeleton - itkBinaryThinningImageFilter3D<br>From: sergio.vera@alma3d.com<br>To: danysunflower@hotmail.it<br>CC: luis.ibanez@kitware.com; insight-users@itk.org<br><br>Hello<br><br>My guess is that the output image is correct, but your visualization software has incorrect window/level values so you cannot see the white (255) pixels.<br><br>Use your software window/level options and try to adjust them until you see the skeleton or use another tool to generate an isosurface from the skeleton.<br>
I often use Seg3D to visualize data because it does not mess with window/level stuff and also does not shown interpolated images so what I see is closer to what the image really is.<br><br>regards<br><br><br><div class="ecxgmail_quote">

<br><br></div><div><div></div><div class="h5">Hi Daniela,<br><br>First you have to verify if the output of the skeletonization<br>filter had indeed all its pixels set to zero.<br><br>You can do this with code similar to<br>

typedef <br> itk::MinimumMaximumImageFilter<ScalarImageType> MinMaxFilterType;<br><br> MinMaxFilterType::Pointer minmaxFilter = MinMaxFilterType::New();<br><br> skeletonFilter->Update();<br>

<br> imageMin = minmaxFilter->GetMinimum();<br> imageMax = minmaxFilter->GetMaximum();<br><br><br> and printing out these values.<br><br> In this way, you will remove the confounding factors of<br><br> * Saving the image in DICOM, and<br>

Thanks for your clarification, now I can compile my code in Release Mode and I have my output in a few seconds.<br><br>Neverthless now I have an other problem that I want to discuss with you. <br><br>My output is an dcm image but its pixels are all black...I can't see the skeleton because in my image all the white pixel disappear.... I think that it is a problem of <span><span><span><span>algorithm's setting and that it erodes too much my image but I don't know how to solve this problem...<br>
Could anyone help me?<br><br>Thanks a lot<br>Daniela<br><br></span></span></span></span><br></div></blockquote></div> <br></div></div><hr>Avatar per Messenger e sfondo per il PC <a href="http://www.experience.windows.com/landing2.aspx?culture=it-it">Creali gratis!</a></div>
