  • Patent number: 12363288
    Abstract: In the method, coded information of a coding unit (CU) in a picture of a video is received from a coded video bitstream. The CU is partitioned into a first partition and a second partition based on a geometric partition mode (GPM). The first partition and the second partition are rectangular partitions that are adjacent to each other and divided by a straight partition line. A first intra prediction mode for the first partition of the CU and a second intra prediction mode for the second partition of the CU are determined. The first intra prediction mode is different from the second intra prediction mode. The first partition of the CU is reconstructed based on the first intra prediction mode and the second partition of the CU is reconstructed based on the second intra prediction mode.

  • Patent number: 12356004
    Abstract: Aspects of the disclosure provide a method and an apparatus for video decoding. The apparatus includes processing circuitry that receives a coded bitstream comprising a first block in a current picture. The processing circuitry obtains prediction information indicating whether the first block is coded in an intra template matching prediction (IntraTMP) mode. If the IntraTMP mode is applied to the first block, the first block is reconstructed based on a prediction block within a reconstructed search area in the current picture. A reference template of the prediction block is matched to a current template of the first block in the IntraTMP mode. An IntraTMP-based block vector BVIntraTMP of the first block is stored. The IntraTMP-based block vector indicates a position displacement between the current template of the first block and the reference template of the prediction block. A second block is reconstructed based on the stored IntraTMP-based block vector.

  • Publication number: 20250215089
    Abstract: Disclosed are an antigen-binding protein targeting PD-L1 and CD40, preparation therefor, and use thereof. The antigen-binding protein targeting PD-L1 and CD40, by means of blocking a PD-1/PD-L1 inhibitory signaling pathway, acting on an activated CD40 receptor, and simultaneously activating an antigen-presenting cell and a lymphocyte, achieves a significant synergistic anti-tumor effect; meanwhile, the activation of the antigen-binding protein targeting PD-L1 and CD40 on an immune cell only occurs at a tumor microenvironment site, so that problems of systemic drug toxicity and side effects are significantly solved, which enables the antigen-binding protein targeting PD-L1 and CD40 to exert an excellent anti-tumor efficacy under very safe conditions.
