3D rotation invariants by complex moments

A generalization of the complex moments from 2D to 3D is described. Group representation theory is used to construct 3D rotation invariants from them. The algorithm for automatic generating of the invariants of hig...

Recognition of Symmetric 3D Bodies

combinations of rotation and reflection symmetries in 3D. We define 3D complex moments on complex moment values is studied. Each particular symmetry pre-defines certain moment values. Th...

3D Non-separable Moment Invariants

In this paper, we introduce new 3D rotation moment invariants, which are composed of non-separable Appell moments. The Appell moments can be substituted directly into the 3D rotation invariants instead of ...

3D rotation invariants of Gaussian-Hermite moments

3D rotation invariants based on orthogonal Gaussian-Hermite moments are proposed in this paper. We present an elegant and easy theoretical derivation of them. At the same time we prove by experiments that the Gaussian-Hermite invari...

Tensor Method for Constructing 3D Moment Invariants

A generalization from 2D to 3D of the tensor method for derivation of both affine invariants and translation, rotation, and scaling (TRS) invariants is described. The method for generation of the 3D TRS invariants of higher orders i...
