Abstract

A novel theorem linking reflectional symmetry and rotational symmetry of the 2D images has been established. This theorem shows that, for a rotationally symmetric image with K ≥1 fold(s) (K-RS1), its number of reflection-symmetric axes must be either K or zero. To the authors' knowledgeno previous studies have shown the constaint relationship between reflectional symmetry and rotational symmetry. Demonstrations on some typical images have shown the exactness of our novel theorem.
