Patent ID: 7254278

Claim:
A method for the post-processing of a digital image (Im) comprising pixels, said digital image being encoded and decoded according to a pixel-block coding technique, said method comprising a classification step ( 6 ) delivering classes (Cl i ), a step of evaluating the degradation ( 5 ) of said digital image delivering a degradation measurement (DM) of said digital image and a filtering step ( 11 ) delivering a filtered digital image (ImF), wherein: said classification step ( 6 ) intended to allocate a class to a block (B j ) of pixels of said digital image (Im), a filter selection step ( 9 ) intended to associate a filter (F 1 ) with a pair of adjacent blocks (B j , B k ) according to their respective classes (Cl m , Cl n ) and the degradation measurement (DM) of said digital image (Im), a filtering decision step ( 8 ) intended to deliver a filtering decision (Dec) for a pair of adjacent blocks (B j , B k ) according to the degradation measurement (DM), said filtering step ( 11 ) intended to filter a pair of adjacent blocks (B j , B k ) by means of its associated filter (F 1 ).
