  • Publication number: 20250150638
    Abstract: An example method of video coding includes receiving a video bitstream for a plurality of encoded pictures. The method also includes deriving, using a first type of frame interpolation, a reconstruction picture for an encoded picture of the plurality of encoded pictures, and determining, based on a signaled indicator in the video bitstream, whether to apply loop filtering to the reconstruction picture. When the signaled indicator has a first value, a decoded picture for the encoded picture is derived by applying one or more loop filters to the reconstruction picture. When the signaled indicator has a second value, the decoded picture is derived without applying the one or more loop filters to the reconstruction picture.

  • Publication number: 20250150592
    Abstract: The various implementations described herein include methods and systems for coding video. In one aspect, a video bitstream includes a current coding block of an image frame and signals a first syntax element for a multi-hypothesis cross-component prediction (MH-CCP) mode. A computing system determines that the MH-CCP mode is enabled to reconstruct each of a plurality of chroma samples of the current coding block using a respective luma sample and one or more neighboring luma samples. The computing device determines a number (N) of model parameters used in the MH-CCP mode for at least the current coding block, and identifies one or more neighboring luma samples of a first luma sample based on the number (N) of model parameters. A first chroma sample that is collocated with the first luma sample is determined based on the first luma sample and the one or more neighboring luma samples.

  • Publication number: 20250136743
    Abstract: Provided are a waterborne polyurethane (WPU) and a preparation method thereof, and a waterborne scratch-off ink and a preparation method thereof. A chain end group or side group of the WPU contains a longer alkyl chain. When the WPU is used in the preparation of the waterborne scratch-off ink, microphase separation may occur during the film-forming process owing to a hydrophobic/hydrophilic interaction between the non-polar long-chain alkyl and polar groups in WPU molecular, resulting in an incomplete film structure, which is beneficial to make the ink be scratched off.

  • Publication number: 20250142061
    Abstract: Various implementations described herein include methods and systems for coding video. In one aspect, a video bitstream includes a current image frame and a first syntax element for a cross-component sample offset (CCSO) mode. The first syntax element indicates whether to generate a first sample offset of a first color sample of the current image frame based on one or more luma samples. An electronic device identifies a first luma sample that is collocated with the first color sample and neighboring luma sample(s) s of the first luma sample. The first luma sample and the one neighboring luma sample(s) are downsampled to generate downsampled luma sample(s) for the CCSO mode. The electronic device determines the first sample offset of the first color sample based on the downsampled luma sample(s), and reconstructs the current image frame at least by adjusting the first color sample based on the first sample offset.

    Abstract: A computing system receives a video bitstream comprising a current picture that includes a first block. The system determines that the first block is encoded using a first reference block and a second reference block. The system identifies a high-level syntax (HLS) flag in the video bitstream that indicates a weighting scheme for using the first and second reference blocks. The system reconstructs the first block using a first set of weighting factors for reference values from the first reference and second reference blocks when the HLS flag has a first value. The system reconstructs the first block using a second set of weighting factors for the reference values from the first and second reference blocks when (i) the HLS flag has a second value and (ii) at least one of the first and second reference blocks is at least partially outside of a corresponding reference boundary.

  • Publication number: 20250126266
    Abstract: Various implementations described herein include methods and systems for coding video. In one aspect, a video bitstream includes a current image frame and a first syntax element. The first syntax element has a first predefined value that indicates that the band offset only mode is enabled to determine a first sample offset of a first color sample based on luma samples, independently of any associated luma gradient of the luma samples. When the band offset only mode is enabled, quantized values are generated based on the luma samples including a first luma sample collocated with the first color sample. A first color sample is classified based on the quantized values to determine the first sample offset of the first color sample. The current image frame is reconstructed at least by adjusting the first color sample based on the first sample offset.
