I successfully applied the following type of registration, and would like to query specific points within the image and get the corresponding displacement for each point in the image.

I have a composite outTx and can’t figure out how to extract singular point transforms through this method. I would like to eventually get the displacement in pixels for specific points throughout the image.

@dzenanz ,
Is there a function that will allow me to pick a certain point in the fixed image, then determine the inverse transform values for the specific point?

Does TrasnformPoint() get the transform applied to the specific point (ie. translation)? I am more interested in the number than just transforming a specific point

@dzenanz I tried using this code, but kept getting errors at this point. Is this because my outTx is a composite transform? Is it possible to invert Composite Transforms?
