  • Patent number: 10405004
    Abstract: A method and apparatus for processing reconstructed video using in-loop filter in a video coding system are disclosed. The method uses chroma in-loop filter indication to indicate whether chroma components are processed by in-loop filter when the luma in-loop filter indication indicates that in-loop filter processing is applied to the luma component. An additional flag may be used to indicate whether the in-loop filter processing is applied to an entire picture using same in-loop filter information or each block of the picture using individual in-loop filter information. Various embodiments according to the present invention to increase efficiency are disclosed, wherein various aspects of in-loop filter information are taken into consideration for efficient coding such as the property of quadtree-based partition, boundary conditions of a block, in-loop filter information sharing between luma and chroma components, indexing to a set of in-loop filter information, and prediction of in-loop filter information.

  • Patent number: 10368053
    Abstract: A receiver sensor captures a plurality of images, at two or more (different) exposure times, of a scene onto which a code mask is projected. The two or more of the plurality of images are combined by extracting decodable portions of the code mask from each image to generate a combined image. Alternatively, two receiver sensors, each at a different exposure time, are used to capture a plurality of images. The first and second images are then combined by extracting decodable portions of the code mask from each image to generate a combined image. Depth information for the scene may then be ascertained based on the combined image and using the code mask.

  • Patent number: 10264281
    Abstract: A method and apparatus for three-dimensional video coding are disclosed. Embodiments according to the present invention apply the pruning process to one or more spatial candidates and at least one of the inter-view candidate and the temporal candidate to generate a retained candidate set. The pruning process removes any redundant candidate among one or more spatial candidates and at least one of the inter-view candidate and the temporal candidate.

In another embodiment, the inter-view candidate is exempted from the pruning process. In other embodiments of the present invention, the pruning process is applied to the inter-view candidate and two or more spatial candidates.

  • Patent number: 10257543
    Abstract: During a video encoding or decoding process, a predicted prediction block is generated for a CU. The CU may have two or more prediction units (PUs). A computing device selects a neighbor region size. After the computing device selects the neighbor region size, samples in a transition zone of the prediction block are identified. Samples associated with a first PU are in the transition zone if neighbor regions that contain the samples also contain samples associated with a second PU. Samples associated with the second PU may be in the transition zone if neighbor regions that contain the samples also contain samples associated with the first PU. The neighbor regions have the selected neighbor region size. A smoothing operation is then performed on the samples in the transition zone.

  • Patent number: 10205945
    Abstract: Methods of encoding and decoding for video data are described in which multi-level significance maps are used in the encoding and decoding processes. The significant-coefficient flags that form the significance map are grouped into contiguous groups, and a significant-coefficient-group flag signifies for each group whether that group contains no non-zero significant-coefficient flags. If there are no non-zero significant-coefficient flags in the group, then the significant-coefficient-group flag is set to zero. The set of significant-coefficient-group flags is encoded in the bitstream. Any significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is non-zero are encoded in the bitstream, whereas significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is zero are not encoded in the bitstream.
