Abstract :
At present, inaccurate results still exist in the output of the printed mathematical expressions recognition system. After the results were analyzed, one kind of method was introduced which unified the printed mathematical formula structure analysis and semantics knowledge. Suitable post-processing for recognition result based on integrative rectification was carried on. Thus printed mathematical formula recognition system gets consummate. The experiment indicates that this method may enhance the accuracy of the system effectively.
