A computational implementation for assigning perceptual meaning and significance to the points in the symmetry is presented. The coloring scheme allows recovery of the features of interest such as the shape skeletons from the complicated symmetry representation. The method is applicable to arbitrary data including color and multi-modality images. On the computational side, for a 256 × 256 binary image, two minutes on a low-end Pentium machine is enough to compute both the distance function and the colored nested symmetries at four scales.
