Abstract
This article focuses on the rehabilitation of people with low vision, concretely on people with central or multiple loss of vision, and the use of new technological devices to assist them in their daily life by improving their ability to see in a better way the world around them, either virtual or real. This particular case refers to users with impaired vision, and the use of digital image processing algorithms to show the hidden areas that the eye can't see, by moving that information to a visible area of the user. For it, we describe the Low Vision algorithm, which is based on "Bresenham algorithm" as a solution to help rehabilitate people with those types of vision problem.
