Detection of rotational symmetry in curves represented by the slope chain code

作者：

Highlights：

• Slope chain code successfully used to detect rotational symmetry in 2D curves.

• A robust method suitable for processing symmetrical or quasi-symmetrical curves.

• High values for common performance metrics after evaluation with great many curves.

• Methodology’s usefulness is demonstrated with three practical applications.
