  annote = {We present our recent model of a diagram recognition engine. It extends
    our previous work which approaches the structural recognition as
    an optimization problem of choosing the best subset of symbol candidates.
    The main improvement is the integration of our own text separator
    into the pipeline to deal with text blocks occurring in diagrams.
    Second improvement is splitting the symbol candidates detection into
    two stages: uniform symbols detection and arrows detection. Text
    recognition is left for postprocessing when the diagram structure
    is already known. Training and testing of the engine was done on
    a freely available benchmark database of flowcharts. We correctly
    segmented and recognized 93.0% of the symbols having 55.1% of the
    diagrams recognized without any error. Considering correct stroke
    labeling, we achieved the precision of 95.7%. This result is superior
    to the state-of-the-art method with the precision of 92.4 %. Additionally,
    we demonstrate the generality of the proposed method by adapting
    the system to finite automata domain and evaluating it on own database
    of such diagrams.},
