<div dir="ltr">Hello,<div>I am attempting to register two 3D images using the CorrelationImageToImageMetricv4, the LBFGSBOptimizer, and a 3DVersorRigidRegistration. Even if I put the same volumes in to the registration for both the fixed and moving image, I get a very low value for correlation. One thought I had was I might be setting the origins incorrectly, as previously in the project the origin was defined as the centre of the image cubes and I have attempted to stay with that convention, and I haven’t found an example in the ITK examples where the origin is set to something other than 0. The other issue might be that the original data is a char array so I had to create a cast filter to change the image to floats, and the origins might be getting confused between the two. If anyone has any thoughts they would be welcome, I can provide source code if that would be helpful.<br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><p>--</p><p>AH<br></p><p><br></p><p>-----------------------------------------------------------------------------------------------</p><p><i>This email and any attachments thereto may contain private, confidential, and privileged materials for the sole use of the intended recipient.
