Inftyreader format software#

The image segmentation algorithm will be developed using some classical methods completed by a fuzzy approach and studying techniques based on the calculus of variations. We are developing the pattern recognition algorithm by using artificial neural networks. In EPUB3, format, mathematical expressions are output using MathML notation. Word XML ouput from InftyReader can be directly imported into Microsoft Word. HR-TeX is a simplified LaTeX-like notation easier 'to read' specially designed for the blinds. The project aims at developing original algorithms of this kind finalized to realization of an OCR that automatic recognizes both text and formulae. In XHTML format, mathematical expressions are output using MathML notation.

Thus, research in this field could open to new horizons and new frontiers.Īn OCR software has two main components: a pattern recognition algorithm and an image segmentation algorithm. However, since there exists a single OCR of this kind, research in this field is still poor and not enough exploited. Presently, the only software able to process whole documents with printed characters and recognize both text and formulae is InftyReader, developed by Japanese universities and designed for necessity of visually impaired people. For instance, in the case of on-line formulae, additional information can be exploited, such as hand motion, information not available in printed documents. The document can also be exported for use in other tools created by Science Accessibility Net including InftyEditor Math-document editor for sighted people. However, the recognition of on-line formulae is a different problem with respect to recognition of printed formulae processed in long documents. Files made with ChattyInfty can be saved in various accessible formats: LaTeX, MathML, PDF, HTML or Microsoft Word XML. On the other hand, many software and studies on the recognition of on-line handwritten formulae can be found. At this stage, Optical Character Recognition software (OCR) are very important for obtaining editable formats that can be made accessible.Ĭurrently, there exist many OCR working on normal texts with optimal performances.

The creation of accessible texts which are primarily available in a non-editable format (e.g., PDF, JPG files) is the most difficult task.
