It's not easy, especially if it's a 3D image. There are lots of complicated papers on the process. For starters, why don't you start with cpselect(), a simple, manual 2D registration using user-selected landmarks. In the help, navigate to this discussion: Image Processing Toolbox -> User's Guide -> Image Registration -> Registering an Image.
Another option is Brett Shoelson's http://www.mathworks.com/matlabcentral/fileexchange/34510-image-registration-gui

First, exclude all pixels that are at the edges that aren't in both of the images - you know, the black triangles that appear at the outer edges when you rotate, scale, and translate the image to make it align with the reference image. Only consider pixels that are common to both images. Then do a subtraction or PSNR or RMS error or something like that.

Siva,
If you are using R2012a, you might also check out the new function imregister. This function can be used to perform automated image registration:
