Abstract

NTT's laboratories are engaged in a wide range of research and development from basic research to applications, and divided into four laboratory groups. As one of those laboratory groups, NTT Science and Core Technology Laboratory Group carries out research and development with three missions in mind: "Conduct research and development on cutting-edge technologies to expand NTT's business domains," "Create new principles and concepts that will revolutionize society," and "Research and develop technologies that are friendly to the global environment and people." We asked Akira Okada, senior vice president of R&D, head of NTT Science and Core Technology Laboratory Group, about the technology strategy of the laboratory group and his mindset as a top manager.

Abstract

In this paper, we propose an OCR system that recognizes the contents of manual writing in handouts. Since the target handouts contain a mixture of Japanese and mathematical formulas, we thought that one type of OCR systems alone would not provide sufficient accuracy. Therefore, in this proposed system, we will consider combining two types of OCR systems. The OCRs to be combined are Tesseract and Mathpix, which are good at recognizing Japanese and mathematical formulas, respectively. When the two OCRs are combined, the final plausible result must be selected, but we wondered if the OCR score could be used as an indicator of selection. The OCR score is a self-evaluation value that is output together with the recognition result. However, there is no guarantee that the OCR score and the actual recognition result show the same tendency. Therefore, in this paper, after classifying the written contents into three categories, words, sentences, and mathematical formulas, we verified whether the recognition results of each OCR can be appropriately selected based on the OCR score. At this point, the result is that further improvement is needed to make the selection based on the OCR score alone. However, if it becomes possible to classify handwritten contents with the proposal system by additional learning etc., it will be possible to analyze the handwritten contents efficiently, and it is expected that it will be possible to improve the handouts and provide feedback to the lesson plan.
