Image Registration

Image registration is based on aligning images of the same object (taken at different times or in different views) in order to extract information from it. Image registration can be applied to medical images to assess the changes and to detect the development of possible abnormalities in a particular area of interest.

A typical example of image registration  applied to mammographic images is shown below.
