Abstract :
This paper deals with the design of a sensory substitution device for rehabilitation of early onset blindness. A visual scene is captured using a TV camera. Image processing achieves edge detection and graded resolution. Each pixel of the processed image is assigned a sinusoid; weighted summation of these sinusoids elaborates a complex auditory signal. Updating rate of this processing of visual scenes in auditory signals is above 12 Hz.
