Abstract
A method for reducing or eliminating coding artifacts in video pictures processed using intra block prediction methods, for example, according to the H.264 standard. The causes of the coding artifacts are identified to be the intra prediction modes with prediction directions that are not in the direction of the raster scan. Filtering the affected blocks with a simple one-dimensional spatial filter will reduce or even eliminate these coding artifacts.
