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

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-Hermi...

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

3D Non-separable Moment Invariants

In this paper, we introduce new 3D rotation moment invariants, which directly into the 3D rotation invariants instead of the geometric moments without violating their invariance. We show ...

Recognition of Symmetric 3D Bodies

The paper deals with the recognition of symmetric three-dimensional (3D) bodies that can be rotated and translated. We provide a complete list of all existing combinations of rotation and reflection symmetries in 3D

Fourier transform III: TSR Invariants

Fourier transform in 1D, 2D and 3D space is a good tool for invariant recognition. The translation, scaling and rotation invariants are demonstrated. All the functions were realized in the Matlab environment....

2D and 3D Image Analysis by Gaussian-Hermite Moments

This chapter introduces 2D and 3D Gaussian-Hermite moments and rotation invariants constructed from them. Thanks to their numerical stability, Gaussian-Hermite moments provide better reconstruction and recognition power tha...

3D Non‑separable Moment Invariants and Their Use in Neural Networks

of a particular orientation of the object in the space. In this paper, we introduce new 3D rotation moment invariants, which are composed of non-separable Appell moments. We show of the proposed invariants on thre...

Scale invariants from Gaussian-Hermite moments

depends on the input image. The scaling invariance property can be coupled with the rotation invariance presented earlier. This approach is applicable in 2D as wellInvariants to image scaling composed of Gaussian–...
