• We identify mirror symmetry planes in single view sketches of polyhedral shapes.
• The approach uses suitable cues to identify algorithmically mirror symmetry planes.
• The approach improves as fast as it considerably reduces the search space.
• The approach scores symmetry planes by their likelihood.
As part of a strategy for creating 3D models of engineering objects from a sketched input, we attempt to identify mirror symmetry planes early in the process. Our input is a 2D line-drawing derived from a single view sketch of a polyhedral shape, and suitable cues are used to identify mirror symmetry planes algorithmically. Previous attempts to simplify the search space use incomplete criteria. In this paper, we further simplify the search space by scoring valid symmetry planes by their likelihood, i.e., we do not assert “this is a symmetry plane” but “this is more/less likely to be a symmetry plane”.
