On the Intrinsic Reconstruction of Shape from its Symmetries

The main question we address is: what is the minimal information required to generate closed, non-intersecting planar boundaries? For this paper we restrict ‘shape’ to this meaning. More precisely, we examine whether the medial axis together with dynamics can serve as a language to design shapes and to effect shape changes, e.g., for modeling, to generate a morph sequence, etc. We represent the medial axis together with a direction of flow along the axis as the shock graph, and examine the reconstruction of shape along each of the three types of medial axis points...
