| Title: | Image processing techniques for braille writing recognition | Authors: | Falcón, Néstor Travieso, Carlos M. Alonso, Jesús B. Ferrer, Miguel A. |
UNESCO Clasification: | 3307 Tecnología electrónica | Issue Date: | 2005 | Publisher: | 0302-9743 | Journal: | Lecture Notes in Computer Science | Conference: | 10th International Conference on Computer Aided Systems Theory | Abstract: | In this paper we present the development of BrailLector, a system able to speak from Braille writing. By means of dynamic thresholding, adaptive Braille grid, recovery dots techniques and TTS software (Text-To-Speech), BrailLector translates Braille scanned images into normal text, and not only that, it speaks the translated text. BrailLector is a robust application with innovative thersholding and Braille grid creation algorithms which detects and read Braille characters with 99.9% of correct symbols and an error variance below 0.012. The conversion time is only 26 sees for double-sided documents by MATLAB programming language. | URI: | http://hdl.handle.net/10553/44105 | ISBN: | 3-540-29002-8 | ISSN: | 0302-9743 | Source: | Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)[ISSN 0302-9743],v. 3643 LNCS, p. 379-385 |
