However, only under certain assumptions does optical flow coincide with the projection of the actual 3D motion to the image plane. Most prominently, transparent and glossy scene-surfaces or changes in illumination introduce a difference between the motion of objects in the world and the apparent motion. In this paper we summarize the types of problems occuring in this field and show examples for illustration.
