A novel algorithm for robust curvature estimation based on sinusoidal curve fitting is proposed. The evaluation of this algorithm is presented on analytical surface triangulations by comparing it with other recognized fitting methods according to three criteria: convergence, precision and robustness. By experimenting on various data, we show that the Sinefitting algorithm is less affected by errors in vertex normal estimation.
