Fig. 4. Two inference rules that are applied successively to a shape. The first rule is the Symmetry-Curvature Duality Theorem, which states that to each curvature extremum, there corresponds a unique symmetry axis terminating at that extremum. The second rule is the Interaction Principle, which states that each of the axes is a direction along which a process has acted. | back to text |
