METHOD OF DETECTING BLOCKING ARTEFACTS

摘要

The invention relates to a method of detecting blocking artefacts within a sequence of digital images. The method comprises a step of high-pass filtering a portion of a digital image, intended to supply at least one card of discontinuity pixels. It also comprises a step of detecting blocking artefacts, intended to detect a first type (p1) of elementary blocking artefact and a second type (p2) of elementary blocking artefact from the at least one card of discontinuity pixels. The method finally comprises a step of correcting the blocking artefacts in accordance with their type (p1, p2).
