  • Publication number: 20170230687
    Abstract: A method and apparatus of image coding including a no-residue prediction mode are disclosed. At the encoder side, current predictors for a current coding unit are determined according to a target prediction process associated with a target prediction mode. The current predictors are determined based on pixel data including reconstructed pixels in the current slice or the current image. The target prediction process is applied to the current coding unit using the current predictors to generate prediction residues. A distortion condition or a cost measure for the prediction residues is determined. If the distortion condition is satisfied or the cost measure favors coding without the prediction residues, the current coding unit is encoded into current compressed bits of the current coding unit without compressed data associated with the prediction residues. A corresponding decoding method and apparatus are also disclosed.

  • Publication number: 20170188026
    Abstract: A method and apparatus of image coding including adaptive entropy coding are disclosed. According to this method, input pixels associated with a group of symbols generated from image or video data are received. Maximum bit-depth of the group of symbols is then determined. If the maximum bit-depth of the group of symbols is smaller than a first bit-depth threshold, the group of symbols is encoded or decoded using Golomb-Rice coding. If the maximum bit-depth of the group of symbols is greater than or equal to the first bit-depth threshold, the group of symbols is encoded or decoded using second entropy coding, where the second entropy coding is different from the Golomb-Rice coding. Outputs corresponding to encoded or decoded output associated with the group of symbols are provided. The maximum bit-depth of the group of symbols is signaled at the encoder or recovered at the decoder by parsing the bitstream.

  • Publication number: 20170134734
    Abstract: Method and apparatus of image coding using block prediction (BP) allowing multiple block sizes are disclosed. According to one method, first distortion for the current block coded using BP with a first block size is derived using at least partial second distortion for the current block coded using BP with a first block size. According to another method, a flag indicating whether the BP using variable block sizes is enabled. According to yet another method, when a current block is coded using BP by partitioning the current block into multiple partitions, predictors for two partitions in different reconstructed pixel line groups are derived from different reconstructed pixel line groups. According to still yet another method, for coding image data in a non-444 color sampling format using BP, the predictors for chrominance pixels in the current block are derived from the predictors for the luminance pixels of the current block.

  • Publication number: 20170105011
    Abstract: A method and apparatus of coding using multiple coding modes with multiple color spaces are provided. For the encoder side, a coding mode is selected from a coding mode group. A corresponding color domain is associated with the coding mode and the corresponding color domain is selected from a color-domain group including at least two different color domains. The current coding unit is then encoded in the corresponding color domain using the coding mode. Furthermore, the syntax of the corresponding color domain is signaled in current coding unit syntaxes. The different color domains may include RGB color domain and YCoCg color domain. According to another method, if the midpoint prediction (MPP) mode is selected, a current block is color transformed into another color domain and the MPP coding process is performed in said another color domain.

  • Publication number: 20170105012
    Abstract: A method and apparatus of encoding using multiple coding modes with multiple color spaces are disclosed. Weighted distortion is calculated for each candidate mode and a target mode is selected according to information including the weighted distortion. Each candidate coding mode is selected from a coding mode group including at least a first coding mode and a second coding mode, where the first coding mode uses a first color space for encoding one block and the second coding mode uses a second color space for encoding one block, and the first color space is different from the second color space. The weighted distortion corresponds to a weighted sum of distortions of color channels for each color transformed current block using a set of weighting factors and the set of weighting factors is derived based on a color transform associated with a corresponding color space for each coding mode.

    Abstract: A method and apparatus of encoding frames with a frame type structure adaptively according to a current encoding status after receiving a request for an IDR frame or receiving an indication of picture data loss are disclosed. If the check result of the current encoding status is true, the second frame type structure is the same as the first frame type structure; and if the check result of the current encoding status is false, the second frame type structure is different from the first frame type structure. Another method and apparatus of encoding frames with a reference frame structure and a frame type structure adaptively according to one or more current encoding statuses after receiving an indication of picture data loss are disclosed. The system may use two different check results to adaptively select the reference frame structure and the frame type structure.
