  • Filtering strength determination method, moving picture coding method and moving picture decoding method
    Publication number: 20080069238
    Abstract: A moving picture coding apparatus including an inter-pixel filter having the filters for filtering decoded image data so as to remove block distortion which is high frequency noise around block boundaries. The filters include a filter A114a, a filter B114b, a filter C114c, and a filter D114d; each having a different filtering strength. The coding apparatus also includes a filter processing control unit for determining a filtering strength of the inter-pixel filter.

  • Picture encoding method and picture decoding method
    Publication number: 20080056380
    Abstract: A picture encoding method of the present invention is a picture encoding method of predictively encoding an input picture with reference to pictures stored in a picture buffer, decoding the encoded input picture, judging whether or not the decoded picture is a picture for reference and whether or not the decoded picture is a picture for output which needs to be stored until its display time, and storing, in the picture buffer, the picture for reference and the picture for output based on the determination result.

  • CODING DISTORTION REMOVAL METHOD, VIDEO ENCODING METHOD, VIDEO DECODING METHOD, AND APPARATUS AND PROGRAM FOR THE SAME
    Publication number: 20080049843
    Abstract: Mosaic-shaped block noise occurs when a compressed video signal is reproduced. This block noise is removed, but removing block noise from every block using a deblocking filter imposes a significant load on the deblocking filter. This load is therefore reduced by determining whether coding distortion removal (deblocking) is necessary, and applying a deblocking filter only when needed.
