Robust Assistive Reading Framework for Visually Challenged

The Main objective of this assistive framework is to communicate the textual Information in the image captured by the Visually Challenged person as Speech, So that the Visually Challenged person can acquire knowledge about the surrounding.This framework can help Visually Challenged person to read books, magazine, warnings, instructions and various displays as well by taking their image along with the surrounding.Then the Optical Character Recognition (OCR) extracts and recognizes the text in the image and generates the text file.This text file is further converted to Speech with the help of Text to Speech (TTS) Synthesis.The inherent problem with the previous approach was if the acquired image is affected with the issues of different lighting conditions, noise and issue of Skew and Blur, as the image is captured by Visually Challenged person.Then the overall accuracy of the system was at stake due to inefficient OCR leads to improper Speech output of TTS Synthesis.In this paper we have introduced two more processes that are deblurring using Blind Deconvolution method and Preprocessing operation to remove the effect of noise and blur.Thus it prepares the image for efficient result of the framework for Visually Challenged.The proposed approach is implemented in Matlab with the image captured manually and taken from the internet and the result along with the OCR text file and corresponding output Speech shows that our framework is better than the previous framework.
