  • Abstract
    In this paper a method for noise reduction in ocular-fundus image sequences is described. Image registration is combined with image enhancement by fusing subsequent frames of the same region. The experimented temporal integration techniques are used to compute enhanced pictures of the overall capillary network. To evaluate the attainable results, the signal-to-noise ratio was estimated before and after restoration
