  • Patent number: 10284847
    Abstract: An image predictive encoding device can efficiently encode an image, while suppressing an increase in prediction information and reducing the prediction error of a target block. In an image predictive encoding device, according to one embodiment, to produce a prediction signal of a partition in a target region, it is decided whether prediction information of a neighbouring region can be used. When prediction information of the neighbouring region can be used, a region width of the partition where the prediction information of the neighbouring region is used to produce the prediction signal is determined. The prediction signal of the target region is produced from a reconstructed signal based on at least one of the region width, the prediction information of the target region, and the prediction information of the neighbouring region. The prediction information, information identifying the region width, and a residual signal are encoded.

  • Patent number: 10284874
    Abstract: Systems and methods are described for encoding and decoding video using derived block vectors as predictors in intra block copy mode. In an exemplary encoding method, an encoder identifies at least a first candidate block vector for the prediction of an input video block, where the first candidate block vector points to a first candidate block. The encoder then identifies a first predictive vector (e.g. a block vector or a motion vector) that was used to encode the first candidate block. From the first candidate block vector and the first predictive vector, the encoder generates a derived predictive vector from the first candidate block vector and the first predictive vector. The encoder then encodes the video block in the bit stream using the derived predictive vector for the prediction of the input video block.

  • Patent number: 10187653
    Abstract: A system includes motion vector prediction circuitry that generates motion vectors for pixel groups and pixel subgroups within the pixel groups. For a current pixel group within the currently processed picture, the motion vector prediction circuitry selects a target reference picture. Without first translating the current pixel group in accord with an offset vector, the motion vector prediction circuitry initiates generation of a default motion vector for the current pixel group. Responsive to the selected target reference picture, the motion vector prediction circuitry generates the offset vector. The motion vector prediction circuitry translates the current pixel group in accord with offset vector and determines motion vectors for pixel subgroups of the current pixel group based on the translated position of the current pixel group.
