Abstract

A method for reducing blurring associated with objects forming part of a grey scale image. The method includes receiving ( ) a set of image pixels and then calculating ( ) a gradient value for each one of the image pixels in the set. A selecting step ( ) selects candidate object edge pixels from the image pixels by comparing the gradient value for each one of the image pixels in the set with a threshold value. A determining step ( ) then determines a distribution of number candidate object edge pixels with specific grey level values. Thereafter, candidate object edge pixels within said distribution that have the same grey level values are identically non-linearly modified at a modifying step
