  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.
