Hello Edoardo,<br><br>To convert a gray level image in RGB image, you can use a CastFilter (<a href="http://www.itk.org/Doxygen/html/classitk_1_1CastImageFilter.html" target="_blank">http://www.itk.org/Doxygen/html/classitk_1_1CastImageFilter.html</a>)<br>

<p><font size="2">Hello<br>
Is there someone that can explain me how can I convert a gray scale image in a RGB image?<br>
for example if I define:<br>
<br>
const unsigned int Dimension = 2;<br>
typedef unsigned char PixelType; <br>
typedef itk::Image< PixelType, Dimension > ImageType;<br>
typedef itk::RGBPixel< unsigned char > ColorPixelType;<br>
typedef itk::Image< ColorPixelType, Dimension > ColorImageType;<br>
ImageType::Pointer input = reader->GetOutput();<br>
// (...) some operations with image<br>
ColorImageType::Pointer image_c;<br>
<br>
now how can I copy image in image_c?<br>
<br>
Thank you very much<br>
Edoardo</font>
</p>
