The present invention is embodied in systems and methods for determining structure and motion of a three-dimensional object using two-dimensional images of the object obtained from multiple sets of views with different projection models, such as from a full perspective view and a weak perspective views. The evaluation step uses statistics relative to previous coded frames to evaluate a complexity of the current frame to be coded. The length of the exposed wire is unimportant. Each antenna element may have one or more loading structures configured to decrease the footprint of the antenna element and minimize the size of the antenna apparatus. The discharged chute directs the received article onto a discharge stacking station. The concept includes a process for providing navigation information including deriving a destination for a first vehicle and determining a present location of the first vehicle.
