Abstract
A method to find symmetries along curved paths in input scenes. The method may detect a curve in an input scene and one or more elements on that curve. The method may define and group points for the one or more element on the curve, and define a centroid for each group. The method may then parameterize a transformation in transformation space between each centroid pair in the input scene. The method may then extract transformation paths by clustering points. The method may create phantom objects in case of mirroring along curved paths to help detect the curved paths.
