A pre-compensation algorithm for different optical aberrations using an enhanced wiener filter and edge tapering

This article is about applying a new pre-compensation method on digital images displayed on computer monitors. The proposed method can be categorized as a deconvolution technique, based on human ocular point spread function (PSF). It's possible to obtain the ocular PSF from “wavefront analyzers”, an accessible optometric apparatus for measuring the optical aberrations of human eye. Optical aberration is any deviation of the optical wavefront from its ideal path. This pre-compensation algorithm that is based on an enhanced local Wiener filter and edge tapering was tested on 8 different types of aberrations. For this purpose, we used the Zernike polynomials to represent the mentioned 8 common varieties of ocular optical aberrations.
