摘要： A video coding method enables reduction in the decrease in the efficiency of coding a video and enhancement of the image quality of the resulting decoded video. The video coding method includes predicting a video signal to generate a prediction signal; calculating, as a prediction error signal, the difference between the video signal and a prediction signal; and generating a reconstructed video signal by reconstructing the video signal based on the prediction signal and the prediction error signal. The video coding method also includes determining filter data items that are used to filter each of at least two of the prediction signal, the prediction error signal, and the reconstructed video signal; and coding the determined filter data items based on the cross correlations between the determined filter data items.

摘要： The present invention relates to coding of an image of a video sequence block wisely and, in particular, to coding of a block of samples, which may be chrominace or luminance samples, or samples of any colour space, by a pulse code modulation (PCM). After PCM coding, deblocking filtering may be applied. The deblocking filter may be selected for the present PCM coded block based on its noise and/or the noise of its adjacent block. The noise of the PCM coded block is indicated by a so-called PCM quantization parameter, which is also encoded in the bitstream.

摘要： The present invention relates to deblocking filtering, which may be advantageously applied for block-wise encoding and decoding of image or video signal. In particular, the present invention relates to automated decision on whether to apply or skip deblocking filtering for a block and to selection of the deblocking filter. The decision and/or selection is performed for predefined individual pixels based on the amount of quantization of the block the boundary of which is to be deblocked and on the amount of quantization of its neighboring block adjacent to the boundary, as well as on the position of the individual pixels.

摘要： The present invention relates to filtering of image data at first with a deblocking and then with an adaptive loop filter, suitable for the purpose of video coding and decoding. In order to reduce requirements to a memory on chip, used to buffer image lines necessary for filtering, the input signal for the adaptive loop filter is determined from among deblocked pixels, non-deblocked pixels and partially (horizontally only or vertically only) deblocked pixels. The adaptive loop filtering of a deblocked pixel may then apply the filter taps to already deblocked pixels and/or undeblocked pixels and/or partially deblocked pixels in accordance with the determination of the input signal. An advantage of the invention is reduction of the line memory necessary especially at the decoder for processing with both filters.
