Hi,<br>You can use either vtkImageMagnitude or vtkImageLuminance.<br><br>HTH<br>Jerome<br><br><div class="gmail_quote">2010/3/4 Christian Werner <span dir="ltr"><<a href="mailto:christian.werner@rwth-aachen.de">christian.werner@rwth-aachen.de</a>></span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hello!<br>
<br>
Maybe I am blind, but I don't find any filters for converting from RGB(3 scalars) to greyscale(1 scalar). I found vtkImageHSVToRGB and such, but not this one.<br>

Best regards,<br>
