    Abstract

    A novel image enhancement algorithm which simplifies image content and enhances image contrast and color saturation is proposed. The capability to improve the image discriminability by patients with central scotoma was evaluated using computer simulation. Image enhancement and discriminability simulation were based on modeling of contrast sensitivity loss for the low vision patient with central scotoma size of ±10 degrees of the visual field. The results are compared with other methods of image enhancement. The simulations results suggest that the proposed method performs well compared with other tested algorithms, showing significant increase in the average image discriminability, measured using the d' parameter.
