In ,  and  a procedure for the reduction of a binary image to a skeleton for the purpose of the automated recognition and classification of images is described. In this work we extend the construction of skeletons to grey level or color images. A hierarchy of decorated graphs are constructed which capture the visual content of the original image to different levels of detail. The correspondence of the decorated graphs to the image is demonstrated by an inverse algorithm which allows the approximate reconstruction of the original image.
