Comparison of images

I have some images of the boundary between 2 fields and need to know if the 'shape' of the boundary is the same in both images. I do not think that it is so would like someone clever with image transformations to compare the 2 and perhaps overlay one on the other.

The 'original' or base boundary is contained in the file - 20230902 - PV - WH Paddock Screenshot - and the questionable one is contained in the file - 20230902 - PV - WH TR1 Screenshot - and it is the red line running left to right at the top of the image.

I have bigger copies if needed but want to add an image for you to see.
