Abstract
The present invention relates to a method of processing a sequence of digital images, intended to detect, in a dynamical manner, a grid comprising blocking artefacts. Said method comprises the steps of, a) detecting () a current spatial grid (SG(t)) within a portion of the image constituted by a current field (FLD(t)), b) determining () a current reference grid (RG(t)) from a current spatial grid (SG(t)) and a preceding reference grid (RG(t-)) supplied by a memory MEM (), the current reference grid (RG(t)) being subsequently stored temporarily in the memory MEM (), and c) correcting COR () blocking artefacts which are present in the current field (FLD(t)) from the preceding reference grid (RG(t-)) so as to supply a processed field (PPP(t)).
