Abstract
The paper deals with moment invariants, which are invariant under general affine transformation and may be used for recognition of affine-deformed objects. The authors' approach is based on the theory of algebraic invariants. The invariants from second- and third-order moments are derived and shown to be complete. The paper is a significant extension and generalization of recent works. Several numerical experiments dealing with pattern recognition by means of affine moment invariants as the features are described.
