Features invariant to linear transformations in 2D and 3D
T.H. Reiss · 2003
Planar objects can be recognized independent of viewpoint using features invariant to affine transformations. Such features can be generated from the image moments using algebraic invariants. This paper shows how to use tensors to generate algebraic invariants in 2D and 3D, and shows that these features are much more robust than affine invariant Fourier descriptors.>
