Symmetry analysis through wave propagation
Mukherjee DP., Brady M.
A significant drawback of the symmetry set evaluation for a 2D shape using the wave diffusion process1 is its slow execution time caused, in large part, by the diffusion step. We first recall the need for a diffusion process. A parallel implementation of the wave diffusion algorithm on a transputer network is presented. A faster alternative approach to detect the symmetry set, which we call the normal transform, and which is similar to the wave propagation mechanism, is described.
