Computer Vision-Based Assistive Technology for Helping Visually Impaired and Blind People Using Deep Learning Framework

Millions of people in this world can't understand environment because they are blind or visually impaired. They also have navigation difficulties which leads to social awkwardness. They can use some other way to deal with their life and daily routines. It is very difficult for them to find something in unknown environment. Blind and visually impaired people face many difficulties in conversation because they can't decide whether the person is talking to them or someone else. Computer vision-based technologies have increased so much in this domain. Deep convolutional neural network has developed very fast in recent years. It is very helpful to use computer vision-based techniques to help the visually impaired. In this chapter, hearing is used to understand the world. Both sight sense and hearing have the same similarity: both visual object and audio can be localized. Many people don't realise that we are capable of identifying location of the source of sound by just hearing it.
