Hi Xavier,
It's a good question, the mesh coordinates for displacement field can be confusing. The displacement field has the spacing of dm = 8. The way it has been setup, it works as 1:dm:519+2, 1:dm:694+3 and 1:dm:120+1. Basically, it asymmetrically pads the image such that, the image size has reminder of 1 when divided by 8. Does it makes sense?
Best,

Then the displacement field in these coordinates has been interpolated after finding its values in the center of each subset, right? So the output displacement is defined in the coordinates in the way you told me. It makes much more sense now.
Thank you very much!

Just a minor correction. The displacement aren't interpolated but calculated at the coordinates as I defined earlier.
On another note, a cleaner way to describe the coordinates will be: 1:dm:size(I,i)+dm
