  abstract =	 "Within the scope of this diploma thesis a new
                  algorithm for the recognition of LATEX-pictures,
                  e.g. line drawings, was developed and
                  implemented. The basic idea of this approach is the
                  use of a regular 2x2/4 pyramid for building up lines
                  and arcs out of the huge mass of single edge
                  points. In this manner the amount of data is reduced
                  and the first step towards recognition of the image
                  is done. The approximation of the edges with lines
                  and arcs is accomplished by statistical
                  methods.
                  In addition to a detailed
                  description of this algorithm, this diploma thesis
                  gives a survey over the state-of-the-art in
                  recognition of line drawings and a report on some
                  experimental results.",
