  • Patent number: 12348746
    Abstract: The present disclosure relates to a method for deriving constructed affine merge candidates. The method includes acquiring one or more control point sets from a decoder. The decoder determines whether a reference index of each control point for the control point set index within the control point set associated with a reference index pointing into a reference picture in a first reference picture list is greater than or equal to zero and each is equal to each other. The decoder also determines whether a reference index of each control point for the control point set index within the control point set associated with a reference index pointing into a reference picture in a second reference picture list is greater than or equal to zero and each is equal to each other. The decoder determines that an affine motion model is available based on the determination result.

  • Patent number: 12348765
    Abstract: A method of subblock-based temporal motion vector prediction is performed at a computing device. The computing device acquires a video bitstream including data associated with multiple encoded pictures. While decoding a current picture in the video bitstream, the computing device selects, according to syntax elements signaled in the video bitstream, one reference picture as a collocated picture of the current picture, and determines a temporal vector between the collocated picture and the current picture from motion information of spatially neighboring blocks of a current code unit (CU) according to a fixed order. Next, the computing device splits the current CU into multiple sub-CUs, obtains a temporal motion vector predictor for each sub-CU from the temporal vector and motion information of a block in the collocated picture that corresponds to a respective subblock of the current picture and decodes the current CU according to the temporal motion vector predictors.

  • Publication number: 20250211761
    Abstract: This application is directed to processing video data that includes a plurality of luma samples and a plurality of chroma samples corresponding to a plurality of pixel groups of a video frame. For each pixel group, an electronic device identifies a respective chroma sample and a set of luma samples and determines an anchor luma sample according to a predefined rule. A chroma refinement value is generated based on the set of luma samples by: obtaining a difference between a respective luminance value of each luma sample in the set and an anchor luminance value of the anchor luma sample, applying a cross component filter to the differences-luminance values of the set of luma samples to obtain a cross component filtering result, and performing a non-linear clipping operation based on the cross component filtering result. The electronic device derives a value of the respective chroma sample using the chroma refinement value.

  • Publication number: 20250211779
    Abstract: A video coder using bilateral template to perform decoder-side motion vector refinement is provided. The video coder receives receiving data for a block of pixels to be encoded or decoded as a current block of a current picture of a video. The current block is associated with a first motion vector referring a first initial predictor in a first reference picture and a second motion vector referring a second initial predictor in a second reference picture. The video coder generates a bilateral template based on the first initial predictor and the second initial predictor. The video coder refines the first motion vector to minimize a first cost between the bilateral template and a predictor referenced by the refined first motion vector. The video coder refines the second motion vector to minimize a second cost between the bilateral template and a predictor referenced by the refined second motion vector.
