[Insight-users] raw image input query

[yogeshgupta at iitb.ac.in]

Hi Luis
Thanks.
But the problem was that I want to change the values of some of the
pixels of the image, so I have to have pixel by pixel access of the
image. Now, I am trying to do that using ImageRegionIterator. Please
guide me if this is right to do that as I am a newbie to ITK.
Thankx again for ur guidance.
regards
Yogesh
