  • Deblocking filtering control
    Patent number: 10869063
    Abstract: A deblocking filtering control involves deciding whether to apply deblocking filtering to sample values in a sample block in a picture and in a neighboring sample block in the picture based on i) a first magnitude modification of sample prediction values in a first prediction block in a reference picture for the sample block and ii) a second magnitude modification of sample prediction values in a second prediction block in the reference picture for the neighboring sample block. The sample block and the neighboring sample block are separated in the picture by a block boundary. This decision to apply deblocking filtering based on magnitude modifications reduce blocking artefacts that may otherwise arise in certain pictures of a video sequence.

  • Video compression through motion warping using learning-based motion segmentation
    Patent number: 10805629
    Abstract: Regions for texture-based coding are identified using a spatial segmentation and a motion flow segmentation. For frames of a group of frames in a video sequence, a frame is segmented using a first classifier into at least one of a texture region or a non-texture region of an image in the frame. Then, the texture regions of the group of frames are segmented using a second classifier into a texture coding region or a non-texture coding region. The second classifier uses motion across the group of frames as input. Each of the classifiers is generated using a machine-learning process. Blocks of the non-texture region and the non-texture coding region of the current frame are coded using a block-based coding technique, while blocks of the texture coding region are coded using a coding technique that is other than the block-based coding technique.
