Abstract:
 
"Digital Image Inverse Filtering for Improving Visual Acuity for Computer Users with Visual Aberrations", (2008)
Alonso Jr. M., Barreto A., and Adjouadi M.

ABSTRACT: In this article we describe an approach for improving the effective visual acuity for computer users with visual aberrations. This research is based on inverse filtering of images, compensating the visual acuity loss introduced by the userís visual aberration. These images, when displayed to the user, will counteract his/her visual aberration. The method described in this article integrates spatial information processing mechanisms to reduce the negative impact of some shortcomings of the inverse filtering solution.
