CA 2719890

A method and an apparatus are disclosed for providing an indication of a level of distortion created by blocking artifacts in an image comprising a plurality of pixels, the method comprising for each pixel in a first given direction, determining a corresponding gradient between the pixel and a neighboring pixel, for each pixel in the first direction, summing each of the corresponding determined gradient in a second direction to provide a plurality of gradient summing values, computing a level of distortion for each of at least one potential block size using at least one of the gradient summing values, determining an actual block size using the computed at least one level of distortion and providing the level of distortion corresponding to the determined actual block size.

La présente invention concerne un procédé et un appareil permettant de fournir une indication d'un niveau de distorsion entraînée par des artefacts de blocage dans une image comportant une pluralité de pixels, le procédé comprenant, pour chaque pixel dans une première direction donnée, la détermination d'un gradient correspondant entre le pixel et un pixel voisin, pour chaque pixel dans une première direction, la sommation de chaque gradient correspondant déterminé dans une seconde direction pour fournir une pluralité de valeurs de sommation de gradient, le calcul d'un niveau de distorsion pour chacune d'au moins une dimension potentielle de bloc au moyen d'au moins une des valeurs de sommation de gradient, la détermination d'une dimension réelle de bloc au moyen dudit au moins un niveau de distorsion calculé et la fourniture du niveau de distorsion correspondant à la dimension réelle de bloc déterminée.
