When I print the parameters for a certain image registration, what point is this translating?? the top left? or the center? I understand that the resulting transform transforms the fixed image to the moving, but what exact point is it transforming??
Hello @elapins,
You’ve been busy posting questions 
.
The transformations map all points, not a specific one. For more details see the transformation notebook referenced in your other post.
Why does it output one value then? Because in an affine transformation, if there is shearing, not all points are going to move the same amount? So how can I query specific points (like the center of the moving image)?
thank you!!!
Each ITK transform class has a TransformPoint() method.
