Mellin polar coordinate moment and its affine invariance

作者:

Highlights:

• Affine invariants constructed by traditional integer order moment are sensitive to noise. To construct invariants with lower (non-integer) order moment, we generalize the order of moment from integer to non-integer, and propose the Mellin polar coordinate moment (MPCM).

• Method is provided for constructing affine invariants by any order MPCM.

• Invariants constructed by lower real order MPCMs are more robust to noise than invariants constructed by traditional moments.
