Abstract
Structures defined by quantities of primitives based on edges are beside textures very essential features for understanding the visual world. A complete set of filters is introduced forming edges or lines of several classes but also crossings of lines or areas characterized by different boarders. It can be shown that it is possible to built such arrangements without restrictions to the size of array they overlapp, useing a hierarchical linking procedure. The inherent problem in processing sequenzes of growing length, combinatorical explosion, is here avoided by the proposed hierarchical system which generalizes the continuity of quantities of primitives by these primitives itself. A second hierarchy, providing building blocks for primitives of 2n-fold size, makes informations from different levels of both hierarchies comparable. This allows to predicate the continuity and smoothness of a picture describing element even if the connectivity is locally destroyed.
