[Insight-users] problem in using itkLabelOverlayImageFilter in 3D

[john smith]

I have made this change in my previous code and now I do not get any errors.
But when I run the algorithm I get very strange results. I get a volume with
confused the red and blue colors and not the blue contour of the label image
added on the initial grayscale 3D image. I hope someone could help as I
cannot understand the reason why I am getting these results.

Thanks in advance
