1. A method for estimating motion of each of a plurality of tessels in an intermediate image relative to a reference image, the method comprising:

  • searching the reference image to find points that lie along epipolar lines in the reference image corresponding to upper-left and lower-right vertices of the tessel, respectively, that result in a best-matching shape, wherein the intermediate image and the reference image are calibrated multiple view images of a static scene captured from different angles and related by known geometry;

    estimating a depth of each of at least two of the vertices of the tessel, wherein the depth is a distance from a point on an object in the scene to the center of a camera; and

    using the depth estimates of the at least two vertices of the tessel to estimate the motion of the tessel relative to the best-matching shape.
