<div dir="ltr"><div><div><div><div>Ok, thanks but my question was more like How can I know which input image type requires a particular filter?<br></div>For example: itk::GradientMagnitudeImageFilter requires the input image to have a float pixel type (as described in the software guide). Where can I find this kind of informations? <br>
<br></div>Thank you.<br><br></div>Cheers,<br></div>Elena<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/12/12 Mauro Maiorca <span dir="ltr"><<a href="mailto:mauromaiorca@gmail.com" target="_blank">mauromaiorca@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Elena,<div><br></div><div>have a look at the ITK software guide (<a href="http://www.itk.org/ItkSoftwareGuide.pdf" target="_blank">http://www.itk.org/ItkSoftwareGuide.pdf</a>), chapter 4 (User's guide -> Data Representation -> Image), it might answer your question.</div>
<div><br></div><div>Section 4.1.1 shows how to create a 3D image with unsigned short pixel data, in summary you have to define your image type as:</div><div><div>typedef itk::Image< unsigned short, 3 > ImageType;<br>
</div><div>If you want to create an image with unsigned int pixel data, you have to replace "unsigned short" with "unsigned int", i.e.</div><div>typedef itk::Image< unsigned int, 3 > ImageType;<br>
</div><div><br></div><div>You can play with the examples that you can find either in your ITK source directory (Examples/DataRepresentation/Image/Image1.cxx, etc etc) or online (<a href="https://github.com/Kitware/ITK/blob/master/Examples/DataRepresentation/Image/Image1.cxx" target="_blank">https://github.com/Kitware/ITK/blob/master/Examples/DataRepresentation/Image/Image1.cxx</a> etc etc)</div>
<div><br></div><div>If you want to cast image types (for example converting from unsigned short to unsigned int), have a look at section "6.3 Casting and Intensity Mapping" of the ITK software guide.</div>
<div><br></div><div>Hope it helps.</div><div><br></div><div>cheers,</div><div>Mauro</div><div><br></div><div><br></div><div><br></div></div></div><div class="gmail_extra"><br>
