Applications of Computer Vision for the Blind and Visually Impaired
Everyday tasks such as traveling, finding directions and reading signs and other documents are very difficult for people with blindness or low vision. Computer vision has the potential to give this population access to some of the same visual information available to normally sighted persons for performing these tasks.The lab is involved in several projects exploring these types of computer vision applications.
1.) Analyzing traffic intersections (i.e. finding a nearby crosswalk to provide proper orientation)
