Geometric features robust to noise of curves in Euclidean space are of great interest for various applications such as machine learning and image analysis. We apply Fels-Olver’s moving frame method (for geometric features) paired with the log-signature transform (for robust features) to construct a set of integral invariants under rigid motions for curves in Rd from the iterated-integral signature.
