An integrated portable vision assistant agency for the visual impaired people

This paper is designed to develop a portable auxiliary system for those visually impaired, such as color blindness or serious low vision, to enhance their visual sensitivity or substitute the original visual function thus improve their life quality. Individual vision model for each user can be constructed and the optimal visual compensation process is designed accordingly. For the blind user, an automatic traffic light recognition function is also integrated into the portable system to help them across the road safely. Experimental results show that the proposed vision assistance works well for the visually impaired in improving the awareness of the surroundings and enhancing the visual perception effectively.
