Hi, I want to use the function imabsdiff so I can obtain the absolute difference between two pictures. The problem is that i get a size error because the centroids of the two pictures are in different positions. How can I make them both coincide, regarding the fact that the object is the same in both pictures. Thank you!

It doesn't work. When I use regionprops I get that the centroids and the axis of each picture are different but I don't know how to change them.

You can calculate the minimum distance between centroid and each side over the two pictures, and then crop out the extra from each image. The result should have the centroids in the same relative position.
