....for both motion estimation techniques are promising, both of these methods will fail when the surface concerned is a surface of revolution and is rotating about its axis of revolution. In this situation, there will be no relative motion of the profiles, thus providing no cues for motions. In [24], Pollick studied human perception of structure and motion from profiles, and found similar results from the human subjects of his experiments. Besides, if the pair of profiles under consideration exhibits symmetry about the image of rotation axis (see figure 6.1) any orientation of the epipolar ....

....that, unlike point or line features [20] the contours do not readily provide image correspondences that allow for the computation of the epipolar geometry, summarised by the fundamental matrix. This characteristic makes the motion estimation difficult even for humans, under certain circumstances [15]. A possible solution to this problem is the use of epipolar tangencies [16, 3] as shown in fig. 5. An epipolar tangency is the projection of the frontier points [3] referred to as fixed points in [17] which is the intersection of two consecutive contour generators. If enough epipolar ....
