Rotation invariants of vector fields from orthogonal moments

作者：

Highlights：

• New rotation invariants of vector fields are presented.

• The invariants are composed of orthogonal Gaussian–Hermite moments.

• The proposed invariants are computationally more stable and more discriminative than similar invariants presented earlier.

• Suitable for template matching in vector fields.
