TV for the Visually Impaired
“Peli’s group discovered that patients suffering from macular degeneration could not perceive high-frequency waves in the visible spectrum, which left them unable to see fine details. In order to give the patient a much better chance of discerning the image, the researchers designed an algorithm that specifically increases the contrast over the range of spatial frequencies that the visually impaired could see: the middle and low frequency waves. Ultimately, Peli says, the system enhances the contrast of the picture, and the result is that the finer details are more evident.”
