Neural visual objects enhancement for sensorial substitution from vision to audition

The purpose of this research is to develop a sensorial substitution system from vision to audition. The intention is to provide a noninvasive solution for people with visual impairment to compensate their disability using brain plasticity. The “prosthesis” is a signal processing system that analyses the visual scene to identify objects of interest and encode them into sound. The encoding should be based on characteristics of the human auditory system so that the generated sounds provide an overview of the visual scene in front of the patient, enabling him to locate each identified object. This should allow people with visual disabilities to move around more easily, even in cluttered environments. This paper describes the image processing to enhance objects from images and gives an overview of the sound encoding.
