<p>A method for reducing code artifacts in block coded video signals, in particular MPEG signals, which provides for executing a post-elaboration step after the reception and decoding of a video signal, said post-elaboration step comprising the steps of taking a first projection in a determined space of a digital image belonging to the video signal and operating on said first projection. According to the present invention said post-elaboration step provides for: a) constructing said first projection (DCT1) of said digital image (IM0) in a determined space; b) constructing within the same space at least a second projection (DCT2) of a modified image obtained from the digital image (IM0); c) reducing the norm distance between said first projection (DCT1) and said second projection (DCT2). <IMAGE></p> |
