Описание: The aim of this project is to create a portable Braille reader. The main objective is to recognize Braille characters from images taken by camera on a mobile phone, convert them into Latin alphabet, and eventually display the output to the user. Solution of this task is based on a visual detection of Braille characters. Input frames from camera are processed one by one using a special algorithm which separates dots in characters from the rest of the image. Afterwards, dots are grouped into particular characters. Finally, every single character is translated and rendered on screen. This application is capable of detecting dots from books at a very high success rate. Reading from other surfaces, e.g., metal, has a good success rate as well. Thus, the application is able to detect dots on informational signs and other captions, which are commonly used. This reader gives people the ability to read text written in Braille used by blind and visually impaired people all over the world.
