  • Publication number: 20140119439
    Abstract: Method and apparatus for intra prediction mode coding and decoding are disclosed. In one embodiment, the encoding and decoding process assigns individual indices and codewords to DC mode and Planar mode respectively. The flag is set if the current intra prediction mode is equal to any of one or more neighboring intra prediction modes. Variable length codes are designed for a remaining mode set. If the flag is not set, the currently intra prediction mode is encoded using the variable length codes. In another embodiment, multiple most probable modes are used. If the current intra prediction mode is not equal to any of the multiple most probable modes, the current intra prediction mode is encoded using variable length codes designed for the corresponding remaining modes according the ranking order of the remaining modes.

  • Publication number: 20140092980
    Abstract: A method and apparatus for intra prediction for a current block using directional intra prediction based on neighboring pixels around the current block are disclosed. Embodiment according to the present invention derives the gradient for the current pixel from the neighboring reconstructed pixels along a prediction direction of directional intra prediction. The gradient derived is used to form the final intra prediction. In another embodiment of the present invention, the intra prediction for slant vertical and horizontal directions is derived based on the neighboring reconstructed pixels in a neighboring row adjacent to the top side of the current block and the neighboring reconstructed pixels in a neighboring column adjacent to the left side of the current block.

  • Publication number: 20140086502
    Abstract: A method and apparatus for chroma intra prediction for a current chroma block with reduced line memory requirement are disclosed. The chroma intra predictor is derived from reconstructed luma pixels of a current luma block using a model with parameters. In various embodiments according to the present invention, the derivation of the parameters relies on a reconstructed luma pixel set corresponding to neighboring reconstructed luma pixels from causal luma neighboring areas of the current luma block, wherein said causal luma neighboring areas include a first area corresponding to reconstructed luma pixels above a horizontal luma block boundary on a top side of the current luma block, and wherein the reconstructed luma pixels from the first area that are included in the reconstructed luma pixel set are from a luma pixel line immediately above the horizontal luma block boundary.

  • Patent number: 8340192
    Abstract: A Wyner-Ziv coding scheme jointly utilizes multiple side information at the decoder is described. A new probability model is introduced based on an extended turbo decoding trellis, so that the transitional probability is calculated from the probabilities conditioned on multiple side information. The proposed scheme handles multiple side information in a multi-dimensional manner to potentially achieve coding performance better than either selecting one side information or generating a single side information by averaging several side information. When the decoder receives multiple streams of parity bits, the conditional probabilities on the parity bits from the multiple streams all contribute in turbo decoding. The errors existing in some of the streams can be automatically eliminated during the decoding process.

  • Publication number: 20120177113
    Abstract: A method and apparatus for improved intra prediction mode coding are disclosed. Intra prediction exploits the spatial correlation within a picture or within a picture region. In practice, a picture is divided into blocks and the intra mode prediction is performed on a block basis. In newer coding systems, multiple intra prediction modes such as Vertical mode, Horizontal mode, DC mode and Diagonal mode, have been used to improve the coding efficiency of intra coding. However, the mode selection information for intra prediction has to be conveyed to the decoder for proper operation. In High-Efficiency Video Coding (HEVC), a coding scheme for the intra luma prediction mode is being considered, where the intra prediction mode of a current block is compared with the minimum of two intra luma prediction modes corresponding to two neighboring blocks.

In newer coding systems, multiple intra coding modes such as Vertical mode, Horizontal mode, DC mode and Diagonal mode, have been used to improve the coding efficiency of intra coding. Furthermore, a Luma_mode has also been used in intra prediction of chroma component to further improve the performance in the High Efficiency Video Coding (HEVC) standard being developed. However, the mode selection information for intra prediction has to be conveyed to the decoder for proper operation. Spatial features in a picture often exist in both luma and chroma components. The intra luma prediction mode and intra chroma prediction mode will have high probability to be the same.
