picture blocks. Claim 1, which claims the method, is
illustrative:
1. A method of improving the visual perception of a
picture, the picture being derived from a decoded picture
signal comprised of blocks of quantized coefficient data
produced by encoding an input picture signal, the method
comprising:
decoding first picture data representing a first
encoded picture block being of an n x m sized group of
pixels and decoding neighboring picture data representing a
neighboring encoded picture block being of an n x m sized
group of pixels;
obtaining the run-length codes of each of the first
encoded picture block and the neighboring encoded picture
block;
deriving filter coefficients based on the run-length
codes of each of the first encoded picture block and the
neighboring encoded picture block;
providing the filter coefficients, the decoded first
picture data and the neighboring picture data to an adaptive
filter for filtering the decoded picture data of the first
and neighboring picture blocks;
filtering the decoded picture data of the first and
neighboring picture blocks; and
producing an outputted filtered picture signal.
