Abstract: The "visual motion estimation" problem concerns the estimation of the motion of an object viewed under projection. This paper addresses the feasibility of such a problem. We will show that the model which defines the visual motion estimation problem for feature points in the Euclidean 3D space lacks both linear and local (weak) observability. The locally observable manifold is covered with three levels of Lie differentiations. It is possible, indeed, to reduce the set of indistinguishable... (Update)
