Construction of Restoration System for Old Books Written in Braille
Braille books follow a process of deterioration different from ordinary printed books. Braille is a reading letter and visually impaired people touch the boss with the finger’s belly. Therefore, in Braille books that are frequently read, Braille is dirty with aged use, holes open, and they collapse. In old Braille books, braille collapses and deteriorates due to pressure from left and right books in the library. Therefore, in this research, we convert Braille books into machine-readable electronic data. First, a Braille book is scanned by an image. Next, we detect braille by image recognition technology one by one from braille page. And we classify and identify Braille. Furthermore, we correct errors such as misdetection of braille and misidentification. Finally, we save the result as character code.
