Deconvolution

A computational process that reverses the blurring effects of convolution in an optical or imaging system. In the context of visual accessibility, deconvolution is used to pre-process images displayed on a computer screen so that when viewed through an eye with known aberrations, the blurring introduced by the eye effectively cancels out the pre-applied transformation, resulting in a clearer perceived image. This technique has potential applications for people with low vision caused by corneal or lens irregularities.
