Abstract

Image Jittering was explored as a way of enhancing the peripheral vision of the AMD-Impaired. In the experiments conducted we studied the visual response of 4 normal subjects to the jittering of a grating image. Results of this study indicate an enhancement in angular resolution of about 40% (14 cpd Vs. 10 cpd) upon image jittering with amplitudes varying between 5 and 10 pixels and temporal frequency varying between 0 to 15 Hz. No significant difference in enhancement was found between orthogonal and parallel jittering motion relative to the grating direction. There was also no significant difference between the 5 and 10 pixel amplitude used. These result suggest that image jittering can be used to enhance the impaired vision of AMD inflicted patients.
