Abstract
The present invention relates to a method of post-processing a digital image (Im) comprising pixels, said digital image being encoded and decoded according to a technique of coding by blocks of pixels. Said method comprises a classification step () intended to allocate a class (Cl) to a block (B) of pixels of said digital image, a step of evaluating the degradation () of said digital image delivering a degradation measurement (DM) of said digital image, a filter selection step () intended to associate a filter (F) with a pair of adjacent blocks (B, B) according to their respective classes (Cl, Cl) and the degradation measurement (DM) of said digital image, a filtering decision step () intended to deliver a filtering decision (Dec) for a pair of adjacent blocks (B, B) according to the degradation measurement (DM) and a filtering step () intended to filter a pair of adjacent blocks (B, B) by means of its associated filter (F) delivering a filtered digital image (ImF). The advantage of such a method is that it is both of low complexity and very effective.
