Braille to Text Translation for Bengali Language: A Geometric Approach

TL;DR

This paper presents a new geometric image processing method for translating Bengali Braille images into text, achieving high accuracy despite challenges like image deterioration and deformation.

Contribution

It introduces a novel geometric approach for Bengali Braille translation that addresses common image issues, filling a gap in language-specific assistive tools.

Findings

97.25% recognition accuracy achieved

Effective handling of image deterioration and deformation

First Bengali Braille translation tool using geometric analysis

Abstract

Braille is the only system to visually impaired people for reading and writing. However, general people cannot read Braille. So, teachers and relatives find it hard to assist them with learning. Almost every major language has software solutions for this translation purpose. However, in Bengali there is an absence of this useful tool. Here, we propose Braille to Text Translator, which takes image of these tactile alphabets, and translates them to plain text. Image deterioration, scan-time page rotation, and braille dot deformation are the principal issues in this scheme. All of these challenges are directly checked using special image processing and geometric structure analysis. The technique yields 97.25% accuracy in recognizing Braille characters.
