Recognizing 3-D Curves from a Stereo Pair of Images: a Semi-differential Approach

摘要: This study investigates how the stereo view of a 3-D curve can be characterized in way that is invariant under Euclidean motions curve. Depending on knowledge about and variability parameters stereo-setup, several transformation groups are identified as framework relevant to extraction invariants. The point-derivative exchange principle used construct new set semi-differential invariants for pairs. resulting range from quite simple rather complicated, but information needed their computation remains limited at all times. Finally, motion sequences well surface shape descriptors proposed special cases.
