Embedding a Mathematical OCR Module into OCRopus

点击翻译按钮获取中文摘要

In this research, we aim to contribute the development of the full text OCR system that is also able to read mathematical expression, and embed our mathematical OCR module to an open source OCR soft OCRopus developed by DFKI(German Research Center for Artificial Intelligence). To increase the affinity between our module and the system, we reviewed the embedding position of our module and utilized the existence functions of the OCRopus. As for the display expression in which the mathematical expression appears as a line independently, our module is able to locate and crop the line automatically, then the cropped line is correctly converted to the Math-ML or the LaTex format.
