  • Publication number: 20260019599
    Abstract: Methods and systems are described for intra-prediction using template matching (TM) in video coding. The proposed methods include adaptive fusion when using template-based intra mode derivation using the most probable modes (TIMD), and fusion in intra mode prediction with template matching (Intra TMP).

  • Publication number: 20250337880
    Abstract: Methods are described for template matching (TM) in video coding. The proposed methods include: the use of constrained top and left neighbors in template matching, enabling TM only in coding tree unit boundaries, using approximated reconstructed samples, a new processing pipeline for deriving decoder side intra mode derivation (DIMD) combined with template based intra mode derivation (TIMD), and using filtered pixels from the neighbors, instead of using the reconstructed pixels. Furthermore, methods are described on how template matching may be applied in combination with Intra, sub-partitioning mode, interpolation filtering in intra prediction, block partitioning, bi-prediction with coding unit-level weights, and adaptive motion vector resolution.

  • Publication number: 20250254301
    Abstract: Methods related to the geometric partition mode (GPM) in video coding are described. The proposed methods include: applying adaptive ordering of merge candidates with template matching (ARMC-TM) to derive GPM inter candidate lists, candidates list applying merge motion vector differences in GPM, enabling GPM for all-intra coding units (CUs), using inter and intra template costs in intra-prediction modes of GPM, using GPM partitions to generate templates in template matching, and using neighboring reconstructed samples and an edge criterion to derive top and left-edge intercepts to generate partitioning candidates.

  • Publication number: 20250254325
    Abstract: Methods, systems, and bitstream syntax are described for sign prediction in video coding. The method include: selection of top and left neighbors based on an image continuity check, the intra mode of the current coded unit (CU), the merge motion vector, or adaptive motion vector prediction, sign prediction based on residue domain of current CU or neighbor CUs, sign prediction based on approximated reconstruction samples, reducing the number of selected coefficients for sorting, simplifying the sequential search cost, and by combining sign prediction with sign data hiding.

  • Patent number: 11477455
    Abstract: Methods, processes, and systems are presented for combining signal reshaping (also referred to as luma mapping chroma residuals scaling) with local illumination compensation (LIC) in video coding. Examples and trade-offs when the LIC model parameters are computed in the original domain, the reshaped domain, or a mixed domain, are presented.
