Thanks Sergio for your suggestions.<br>I try to use the filter who suggested me but I have some problem and it doesn't run.<br><br>I wrote this code:<br>-------------------------------------------------------------------------------------------------------------------------------------------------<br>
typedef itk::AddConstantToImageFilter<InputImageType,const float,OutputImageType> AddCostantType;<br><br>AddCostantType::Pointer filterCost= AddCostantType::New();<br><br>filterCost->SetConstant(-0.5);<br>filterCost->SetInput(filter->GetOutput);<br>
<br>filterCost->Update();<br>-----------------------------------------------------------------------------------------------------------------------------------<br><br>But I have this output:<br><br>/home/daniela/Scrivania/Skeleton_ok/DistanceTrasform/DistanceTrasform2.cxx: In function ‘int main(int, char**)’:<br>
/home/daniela/Scrivania/Skeleton_ok/DistanceTrasform/DistanceTrasform2.cxx:124: error: no matching function for call to ‘itk::AddConstantToImageFilter<itk::Image<signed char, 3u>, const float, itk::Image<short int, 3u> >::SetInput(<unresolved overloaded function type>)’<br>
<br>[...]<br><br>I included the itkAddConstantToImageFilter.h file in the same folder where I save my code (as I always do when I use header file not included in itk folder...). <br>I thinks that I'm doing a stupid error, but I'm not expert in itk and c++, so I need your help.<br>
<br>Thanks of all, <br>Regards<br><font color="#888888">Daniela<br></font><div class="ecxhm"><hr>Date: Fri, 6 Aug 2010 10:52:11 +0200<br>Subject: Re: [Insight-users] (no subject)<br>From: <a href="mailto:sergio.vera@alma3d.com">sergio.vera@alma3d.com</a><br>

Hi Daniela.<div><br></div><div>Matlab and ITK are completely different environments... it may take a while to adapt.</div><div><br></div><div>To substract 0.5 to a image you can use the following filter: <span style="font-family: Geneva,Arial,Helvetica,sans-serif; font-weight: bold;">itk::AddConstantToImageFilter</span></div>
<div><span style="font-family: Geneva,Arial,Helvetica,sans-serif; font-size: 14px;"><div><span style="font-size: small;"><span style="font-weight: normal;"><br>
</span></span></div><div><span style="font-size: small;"><span style="font-weight: normal;">to perform the comparation between the images you can use </span></span><span style="font-weight: bold;"><span style="font-size: small;">itk::DifferenceImageFilter</span></span></div>
<div><span style="font-weight: bold;"><span style="font-size: small;"><br></span></span></div><div><span style="font-size: small;">regards</span></div>

Hi everyone,<br>I'm working in itk and I have a problem.<br><br>I have to do this operation :<br>-----------------------------------------------------------------<br>if (Daverage < (D - 0.5)) (*)<br> Dfinal=1<br>
else<br> Dfinal=0<br>-----------------------------------------------------------------<br>where:<br><br>D= is a DistanceMap obtained with itkDanielssonDistanceMapImageFilter;<br>Daverage = is D filtered with itkDiscreteGaussianImageFilter;<br>
<br>Dfinal = is a 3D map where pixel are black or white depending from (*).<br><br>I'm trying to do it but I have several problems with operations/comparisons between images... Could anyone help me?<br><br>For example in Matlab I can simply do:<br>
D - 0.5<br>to substract 0.5 to every pixel of my image... I tryed to do the same in itk but it doesn't run...<br><br>Thanks all for help<br>Daniela<br> </div>
