3D AFFINE MOMENT INVARIANTS
Ai La · 1998
Moment Invariants are the descriptor of an object. With the development of the acquisition of 3D information, the direct recognition of 3D objects becomes possible. In this paper, we discuss moment invariants in algebriac forms. Under 3D affine transformations, we extend the algebriac invariants to 3D. Six affine invariants are explicitly derived, which can be used as library functions.
