Hi,
I was hoping someone might beable to help me with a way to convert the =
mutual information metric to a normalized MI metric which is independant =
of the amout of overlap between the fixed and moving images.=20

The following paper explains the theory but I have not been able to =
figure out how to implement it in itk.
C. Studholme, D.J. Hawkes, and D.L.G. Hill, \An overlap invariant =
entropy measure of 3d medical image alignment," Pattern Recognition, =
vol. 32, pp. 71-86, 1999.

I have been using itk release 1.2, is there any new relavent =
developments in 1.4?

Jess
