A Mobile Application for Braille to Black Conversion
- 2k Downloads
This work aims to the production of inclusive technologies to help people affected by diseases. In particular, we present a pipeline to convert Braille documents, acquired with a mobile device, into classic printed text. The mobile application 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 developed 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.
