[Insight-developers] ITK Image orientation fixes with regards to Demons filters

Sat Nov 15 08:56:10 EST 2008

Hans,

I modified the SymmetricForcesDemonsRegistrationTest to set a
direction for both fixed and moving. I made the directions the same
for both fixed and moving. I use a simple rotation matrix for the
directions. When I do this, the test fails.

I have not checked in the new test. Have you tried the new code with
images that have non-identity directions?

Bill
