Without doubt, our visual perception of motion is fundamental to our understanding of and our interacting with the world. It is one of the primary methods by which we determine the relative motion between different objects, including our own motion (egomotion) through the world. It is also a rich source of information about the depth and surface structure of objects, since the variations in viewpoint caused by motion convey three-dimensional structure in much the same way as two views do in the context of stereopsis. It is thought to be important for passive aspects of scene interpretation and object recognition, as well as tasks required for active exploration.
