[Insight-users] how to map grayscale to color

[Gaëtan Lehmann]

Hi,

You may want to look at the label overlay contribution I have submited to  
the insight journal.
It produce a similar result, but with a more distinct set of colors and  
some options to manage the background. Another class in this contrib let  
you show the labels superimposed onto the original image.

All the colored images in the following article where also obtained with  
those classes:

Regards,

Gaetan
