remove horizontal shifts in image

Subject: remove horizontal shifts in image

I would like to remove shifts in horizontal image lines that arise from oscillations in the object. The images are SEM type, obtained via linescans that can vary from 20 to 120 seconds for the full scan. Pixels are 1024 by 788 in the 8-bit image. These can be jpg or tif format. This is a 'registration' problem I believe, but I have not been able to locate anything that can be used for a problem like this.

Can you show us a picture please?

Do you have the image processing toolbox? If so, did you look up
image registration in the help? It shows you how to do it with
cpselect().
