The problem of estimating rigid motion from projections may be characterized using a nonlinear dynamical system, composed of the rigid motion constraint and the perspective map. The time derivative of the output of such a system, which is called the \motion eld" and approximated by the \optical ow", is bilinear in the motion parameters, and may be used to… (More)
