Given a pair of stereo images, epipolar rectification (or simply rectification) determines a transformation of each image plane such that pairs of conjugate epipolar lines become collinear and parallel to one of the image axes (usually the horizontal one). The rectified images can be thought of as acquired by a new stereo rig, obtained by rotating the original cameras. The important advantage of rectification is that computing stereo correspondences is made simpler, because search is done along the horizontal lines of the rectified images. Here a proposed method at Dr. Fusiello's web page is tested with MSR stereo video data "Ballet" and "break Dancers".
