Hi everyone!<div><br></div><div>I have the following routine:</div><div><br></div><div><div>void applyFilter(InternalImageType::Pointer image, itk::ImageToImageFilter&lt;InternalImageType,InternalImageType&gt;::Pointer filter)</div>

<div>{</div><div><span class="Apple-tab-span" style="white-space:pre">        </span>if (!checkImageLoaded())</div><div><span class="Apple-tab-span" style="white-space:pre">                </span>return;</div><div><span class="Apple-tab-span" style="white-space:pre">        </span>statusbar-&gt;showMessage(&quot;Applying filter: &quot;+QString(filter-&gt;GetNameOfClass()));</div>

<div><span class="Apple-tab-span" style="white-space:pre">        </span>filter-&gt;SetInput( image );</div><div><span class="Apple-tab-span" style="white-space:pre">        </span>filter-&gt;Update();</div><div><span class="Apple-tab-span" style="white-space:pre">        </span>image=filter-&gt;GetOutput();</div>

<div><span class="Apple-tab-span" style="white-space:pre">        </span>updateVisualizing();</div><div><span class="Apple-tab-span" style="white-space:pre">        </span>resetVisualization();</div><div><span class="Apple-tab-span" style="white-space:pre">        </span>statusbar-&gt;showMessage(&quot;Ready&quot;);</div>

<div>}</div></div><div><br></div><div>and it is invoked like this:</div><div><br></div><div><div>typedef itk::SmoothingRecursiveGaussianImageFilter &lt; InternalImageType, InternalImageType&gt; FilterType;</div><div>FilterType::Pointer filter = FilterType::New();</div>

<div>filter-&gt;SetSigmaArray(myImage-&gt;GetSpacing());</div><div>applyFilter(myImage, (itk::ImageToImageFilter&lt;InternalImageType,InternalImageType&gt;::Pointer)filter);</div><div><br></div></div><div>However, the above code produces no effect (the image does not change). When content of &quot;applyFilter&quot; is copied to invocation points, it works.</div>

<div><br></div><div>What am I doing wrong?</div><div><br></div><div>Regards,</div><div>Dženan</div>
