Patent ID: 8885969

Claim:
A method for detecting coding artifacts in an image, comprising: filtering, with circuitry, the image with a block noise filter to at least reduce block noise in the image; detecting, with the circuitry, an edge position of an edge in said image after filtering with the block noise filter; detecting, with the circuitry, a border position of a border between a texture area and a flat area in said image after filtering with the block noise filter; defining, with the circuitry, the area between said edge position and said border position as artifact area potentially comprising coding artifacts; displaying artifact location information corresponding to the coding artifacts on a display, the artifact location information including a scalar image map; defining a dilated edge area at least on the side of the detected edge position facing the detected border position, in particular on both sides of the detected edge position; defining a dilated border area at least on the side of the detected border position facing the detected edge position, in particular on both sides of the detected border position; and defining the overlapping area of said dilated edge area and said dilated border area between said edge position and said border position as said artifact area.
