I'm performing a linear transform registration between multiple 2D images. Knowing that my images are only moving in the X direction, the algorithm is occasionally giving me erroneous measurements in the Y direction. Is there any way to limit the transform parameters to 1 direction? How can I implement the registration, metrics, etc. to find the best metric value by only the variation of the X parameter. Thank you in advance.
