Rectifies a stereo pair with known camera calibration using a simple algorithm described in  such that the epipoles project to infinity along the x-axis. After rectification both images will have the same intrinsic calibration matrix, same extrinsic rotation matrix, but the optical centers are not modified.
The calibration matrix is the standard upper triangular matrix used throughout the library. A single calibration matrix is computed for both images by averaging the two original and setting the skew to zero.
The rectified view is chosen such that it will be most similar to the first camera. This is done by making the original z-axis and the rectified z-axis similar.
