Abstract
A compression artifacts removal algorithm that is adaptive
to the artifact visibility level of the input video signal is
proposed. The artifact visibility is determined per frame by
the ratio of the accumulated gradient on the block edges to
that of the remaining area. The filtering of each video frame
is optimized using a least mean square mechanism which
trains on pairs of target images and decompressed images of
similar quality as the input frame. Experimental results
show that the proposed approach outperforms several recent
methods in coding artifact reduction.
