Functions for aligning images by rotation and translation:
MI2 - calculating Mutual information
joint_h - calculating Joint histogram

Mutual information is calculated using joint histogram calculation between two images.

rotate_image.m function by Ohad Gal is used. DO NOT FORGET DOWNLOAD THE FILE:

Users having access to IP toolbox can download which uses IMROTATE function and has an option to crop the image to save computation time.

For each angle of rotation all translation parameters are checked.

NOTE - the images must have correct relative sizes with respect to each other (no resizing is incorporated in this registration)
