Re Karthik,<br> thx for your reply.<br> i changed the place of m_Eigen->Modified() before the m_Eigen->Update method<br> but nothing changed, and i still having the same pb.<br> still waiting for a rescue ;o)<br> Regards.<br><br><b><i>Karthik Krishnan <Karthik.Krishnan@kitware.com></i></b> a écrit :<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> In general there shouldn't be a reason to call Modified() in ITK <br>filters, the pipeline mechanics should take care of that. In your case, <br>you are changing the pixel values with the SetPixel( .. ) method on the <br>image. Unlike most other methods, image->SetPixel(.. ) will not change <br>the modified time of the image. (It would be very inefficient to check <br>every time if a pixel value is different from what it was and set an <br>MTime, during a SetPixel call).<br><br>So you might consider having the line m_Eigen->Modified() *before*, not
<br>after the update method.<br><br>charfeddine amir wrote:<br><br>> Hi Kevin,<br>> thx for reply<br>> i tried the filter->Modified too but it doesen't refresh it.<br>> I'm using a pipeline of filter:<br>><br>> m_Hx = GaussianFilterType::New();<br>> m_Hy = GaussianFilterType::New();<br>> <br>> m_Hx->SetDirection( 0 );<br>> m_Hy->SetDirection( 1 );<br>> <br>> m_H1x = GaussianFilterType::New();<br>> <br>> m_H1x->SetDirection( 0 );<br>> <br>> m_H1x->SetOrder( GaussianFilterType::FirstOrder );<br>> <br>> m_H1xy = GaussianFilterType::New();<br>> m_H1xy->SetDirection( 1 );<br>> m_H1xy->SetOrder( GaussianFilterType::FirstOrder );<br>> <br>> m_H2x = GaussianFilterType::New();<br>> m_H2y = GaussianFilterType::New();<br>> <br>> m_H2x->SetDirection( 0 );<br>> m_H2y->SetDirection( 1 );<br>>
