Image registration

any ideas on how to do a simple image registration (i have IMAGE1 and IMAGE2 taken from the same subject, but with the camera moves a little and you want to match IMAGE2 with IMAGE1)? I checked A LOT of programs to do this, but they all focus on medical imaging, so I was unable to enter a plain JPEG (one even enabled PGM, but didn't work).

thank

There is a great package called "ANTS" that you should link to:

To solve this problem, you need to break it down into manageable steps. 1. You should have a set of similar points (usually determined by feature detection) or user selection. 2. Once you have the points you need, you need to find the transformation matrix between the two images (based on the points you got). 3. Use a transformation matrix to translate one image to another.

Things that can help:



  • Feature detection algorithms: SIFT
  • The topic that it is in computer vision: Stitching of photos, Homography, Registration of images.
