Automatic Braille to Black Conversion
The aim of this work is related to the production of inclusive technologies to help people affected by diseases, like the blindness. We present a complete pipeline to convert scanned Braille documents into classic printed text. The tool has been thought as support for assistants (e.g., in the education domain) and parents of blind and partially sighted persons (e.g., children and elderly) for the reading of Braille written documents. The software has been built and tested thanks to the collaboration with experts in the field . Experimental results confirm the effectiveness of the proposed imaging pipeline in terms of conversion accuracy, punctuation, and final page layout.
