Segmentation and recognition of symbols within handwritten mathematical expressions
M. Koschinski, Hanspeter Winkler, M. Lang · 2002
An efficient on-line recognition system for symbols within handwritten mathematical expressions is proposed. The system is based on the generation of a symbol hypotheses net and the classification of the elements within the net. The final classification is done by calculating the most probable path through the net under regard of the stroke group probabilities and the probabilities obtained by the symbol recognizer based on hidden Markov models.
