InftyReader is the software developed in Kyushu University to recognize mathematical documents including various formulas of pure and applied mathematics. It uses commercial OCR engines to recognize ordinary text parts. One of the crucial points to keep high accuracy of the recognition is the segmentation of the text area and math expression area to combine commercial OCR and InftyOCR. Recently, we are trying to use the OCR engine of ABBY FineReader to adapt InftyReader to various European languages. In the talk, I will briefly sketch the methods to combine different OCR engines and will give some demonstrations of the current state of our New InftyReader.
