Algorithms and Techniques for Image to Sound Conversion for Helping the Visually Impaired People - Application Proposal

This paper presents a system that transforms images acquired with a camera into sounds. The system is designed for the visually impaired people and will convert real time images into sounds, respecting a certain algorithm, to preserve the visual information, but not forgetting the limitations imposed by the human hearing system. The resolution used for images to be conversed is to be found out after some future tests and statistics. The hardware implementation will have to use the capabilities of a portable device, such as a PDA or mobile phone or special built embedded system with microcontroller, and the images will be received though a small web-cam. Actual results obtained by this system configuration are to be evaluated within testing.
