Abstract
A method and system for extracting motion and structure from a sequence of images stored on a computer system, the method comprises obtaining images including a set of three-dimensional (3D) points over a plurality of frames, determining an instantaneous motion of the set of 3D points by an angular velocity and a translation with respect to an axis of rotation, computing an optical flow using the instantaneous motion of the set of 3D points based on a projection of velocity of the set of 3D points, computing a depth of the set of 3D points from the optical flow, and determining an epipolar line in the images using the optical flow.
