Yonghua Li, Kejun Wang, Wei Shangguan, Liqun Tang · 2008
As a long time, the mathematical formula recognition has become one important problem in OCR research field, how to recognize the formula in magazine or book exactly and quickly has become one difficult task. In general, the formula recognition problem could be divided into character segmentation and structure analysis two stages. In this paper, the whole recognition process was studied in detail, using character over-segmentation method and BST character structure analysis algorithm, the general formula could be recognized and remerged successfully, and the recognition ratio is very high. As we can conclude from the experiment result that the mathematical formula recognition method base on baseline structure analysis could satisfy the need of most situations.
