  annote = {This contribution advocates that two-dimensional
    context-free grammars can be successfully used in the analysis of
    images containing objects that exhibit structural relations. The
    idea of structural construction is further developed. The approach
    can be made computationally efficient, practical and be able to
    cope with noise. We have developed and tested the method on a
    pilot study aiming at recognition of off-line mathematical
    formulae. The other novelty is not treating symbol segmentation in
    the image and structural analysis as two separate processes.  This
    allows the system to recover from errors made in initial symbol
    segmentation. },
