  • Patent number: 10123011
    Abstract: Reconstructed picture quality for a video codec system may be improved by categorizing reconstructed pixels into different histogram bins with histogram segmentation and then applying different filters on different bins. Histogram segmentation may be performed by averagely dividing the histogram into M bins or adaptively dividing the histogram into N bins based on the histogram characteristics. Here M and N may be a predefined, fixed, non-negative integer value or an adaptively generated value at encoder side and may be sent to decoder through the coded bitstream.

  • Publication number: 20180316937
    Abstract: Methods, systems, and computer program products for the generation of multiple layers of scaled encoded video data compatible with the HEVC standard. Residue from prediction processing may be transformed into coefficients in the frequency domain. The coefficients may then be sampled to create a layer of encoded data. The coefficients may be sampled in different ways to create multiple respective layers. The layers may then be multiplexed and sent to a decoder. There, one or more of the layers may be chosen. The choice of certain layer(s) may be dependent on the desired attributes of the resulting video. A certain level of video quality, frame rate, resolution, and/or bit depth may be desired, for example. The coefficients in the chosen layers may then be assembled to create a version of the residue to be used in video decoding.

  • Patent number: 10045041
    Abstract: Techniques for inter-layer residual prediction are described. In one embodiment, for example, an apparatus may comprise an encoding component to determine whether a predicted motion for an enhancement layer block is consistent with a predicted motion for a collocated lower-layer block, determine whether to apply inter-layer residual prediction to the enhancement layer block based on whether the predicted motion for the enhancement layer block is consistent with the predicted motion for the collocated lower-layer block, and in response to a determination that inter-layer residual prediction is to be applied to the enhancement layer block, generate a predicted residual for the enhancement layer block based on a residual for the collocated lower-layer block and generate a second-order residual for the enhancement layer block by comparing a calculated residual to the predicted residual.

  • Patent number: 9769475
    Abstract: Techniques to identify one or more candidate reference blocks used to generate a prediction block to encode a current coding block. The candidate reference blocks can be in the same layer as the current coding block or a different layer. In addition, the candidate reference blocks do not have to be co-located with the current coding block. Motion vectors and shift vectors can be used to identify the one or more candidate reference blocks. In addition, uniform and non-uniform weighting can be applied to the one or more candidate reference blocks to generate the prediction block. Accordingly, an encoder can determine and identify reference blocks to a decoder that can provide desirable rate-distortion cost.
