A Novel Shape Descriptor: Gaussian Curvature Moment Invariants

The moment descriptor is combined with Gaussian curvature for three-dimensional shape representation and a novel three-dimensional shape descriptor combined local with global representations is proposed in this paper. Normalization process to the new moment invariants is presented and their independence to the translation, rotation and scaling transforms is proved. Experiments indicate a better classification result to objects with slight different shape characteristic compared with some traditional approaches without increasing the running complexity.
