Abstract
The necessary and sufficient conditions that an object should
satisfy so that motion can be uniquely determined by a direct method are
discussed. This direct method, based on the temporal-spatial gradient
scheme, can estimate the three-dimensional (3-) motion parameters of a
rigid moving object from an image sequence, by utilizing depth
information of the object. It is shown that the 3-D motion cannot be
uniquely determined for only eight kinds of objects with special
geometric structure and surface pattern
