Abstract: Symmetry is a fundamental property of many objects of interest allowing us to simplify computation or reduce complexity and is also a contributing factor of beauty for a human brain. In this work, we try to identify polylines satisfying the local reflection symmetry of polygons and show how to use them for shape characterization, segmentation or to find global approximate reflection symmetries. We describe an algorithm based on a sweep-line paradigm to efficiently compute the polylines by scanning through a polygon at various angles.
