Take a look at the documentation for this class, here :

http://www.itk.org/Doxygen/html/classitk_1_1LabelOverlayImageFilter.html#_details

and look at the insight journal article it links to.

That the documentation refers to color mapping makes me think that the
output image type must be something like :

typedef itk::Image< itk::RGBPixel< unsigned char>, 3> OutRGBImageType;

Also the pixel type of short is small for a label image, but it could be
fine as long as you don't have very many segments.
