We develop a symmetry-based computer analysis and synthesis platform that, given a digitized image of a real-world papercut-pattern, is able to (1) identify dihedral and frieze symmetry as well as asymmetric sub-patterns of the input; (2) generate a fold-then-cut plan that can be used to recreate the input papercutpattern; and (3) synthesize new papercut patterns by varying the motif automatically extracted from the input, or by varying the symmetry group describing the structural organization of the input papercut pattern. We formalize a papercut-pattern as a composition of multiple sub-patterns that are either reflection symmetric (with dihedral or frieze symmetry groups) or reflection asymmetric.
