We do not update the downloads every time a bug is fixed. Its only done when they cumulate to sufficient number. Please get the ITK-3-18 branch via CVS and it should have the fix.<br><br>Thanks<br>--<br>karthik<br><br><div class="gmail_quote">

Forgive me, but does this:<br><br><b>>and it has been backported today to the 3.18 branch by Luis</b><br><br>means that fresh downloads of the ITK 3.18 have this bug corrected? As I've redownloaded it and the modification date for this files are old...<br>

<div style=""><div>Hi Rahul,</div><div> the fixed itkHessianRecursiveGaussianImageFilter is in the ITK CVS repository (Insight/Code/BasicFilters) and it has been backported today to the 3.18 branch by Luis. The test is in Insight/Testing/Code/BasicFilters.</div>
<div>To test your program you'll have to checkout ITK from there and build it, and then compile your program against it.</div><div><br></div><div>As a cheap alternative for testing purposes, you can download the incriminated file (<a href="http://public.kitware.com/cgi-bin/viewcvs.cgi/Code/BasicFilters/itkHessianRecursiveGaussianImageFilter.txx?revision=1.10&root=Insight&view=markup%29" target="_blank">http://public.kitware.com/cgi-bin/viewcvs.cgi/Code/BasicFilters/itkHessianRecursiveGaussianImageFilter.txx?revision=1.10&root=Insight&view=markup)</a>, put it in your own source tree at Insight/Code/BasicFilters (i.e. replacing your own version of the file) and compile your program.</div>

</font><br>Hi all,<div style="margin: 0px;"> this is a heads up message on a bug that Oleksandr Dzyubak has found in itkHessianRecursiveGaussianImageFilter</div><div style="margin: 0px;">(bug 0008990 in Mantis,<span> </span><a rel="nofollow" href="http://public.kitware.com/Bug/view.php?id=10599%29" target="_blank">http://public.kitware.com/Bug/view.php?id=10599)</a><span> </span>and for which I recently submitted a fix.</div>
<div style="margin: 0px;"><br></div><div style="margin: 0px;">The bug affected the behavior of the filter when NormalizeAcrossScale is set to true with dimensions > 2, and it has effects on multi-scale vesselness filters or multi-scale shape-detection filters in general (e.g. those using itk::MultiScaleHessianBasedMeasureImageFilter), and vessel-enhancing diffusion filters.</div>
<div style="margin: 0px;"><br></div><div style="margin: 0px;">The bug caused incorrect normalization of the Hessian across scale-space, and, for instance, lead to a poor performance of vesselness filters when spanning several scales (vessels at smaller scales were washed out compared to how they appear after the fix).</div>
<div style="margin: 0px;"><br></div><div style="margin: 0px;">The fix has been committed after 3.18 was released, hence it will be in for ITK > 3.18. There is now a test (itkHessianRecursiveGaussianImageFilterScaleSpaceTest) that tests the scale-space behavior of the class quantitatively.</div>
<div style="margin: 0px;"><br></div><div style="margin: 0px;">So, for whoever was using multi-scale Hessian-based filters in 3D and higher, please rerun your tests, since there's a very good chance (100% ?) that the results will have changed (most likely for the better).</div>
<div style="margin: 0px;"><br></div><div style="margin: 0px;">I'm here for any clarification. Again, kudos to Oleksandr Dzyubak who highlighted the misbehavior through lots of testing.</div><div style="margin: 0px;">
