  • Patent number: 12382086
    Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. An apparatus for video decoding includes processing circuitry that decodes prediction information for a current block in a current coded picture. The prediction information indicates a motion vector predictor index (MVP_idx) for selecting a motion vector predictor in a motion vector predictor list. The processing circuitry determines whether the MVP_idx is smaller than a threshold. When the MVP_idx is determined to be smaller than the threshold, the processing circuitry decodes a motion vector difference (MVD) corresponding to the motion vector predictor and reconstructs the current block based on the motion vector predictor and the MVD. When the MVP_idx is determined to be equal to or larger than the threshold, the processing circuitry reconstructs the current block based on the motion vector predictor without the MVD which is not signaled in the coded video sequence.

  • Patent number: 12368857
    Abstract: One or more intra mode predictors of a current block are determined, where the one or more intra mode predictors are derived based on the neighboring samples of the current block via either a decoder side intra mode derivation (DIMD) or a template-based intra mode derivation (TIMD). Whether a position dependent intra prediction combination (PDPC) is to be applied is determined based on the one or more intra mode predictors. In response to the determining that the PDPC is to be applied, a fusion process is performed on the one or more intra mode predictors to combine the one or more intra mode predictors into a single intra mode predictor. The PDPC is applied based on the single intra mode predictor to generate a modified predictor of the current block. The current block is reconstructed based on the modified predictor generated by the PDPC.

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.

  • Publication number: 20250223659
    Abstract: The present disclosure relates to enzymatic cascade reactions for achieving better sensitivity in detecting a target nucleic acid sequence. Several aspects of the disclosure relate to a reaction master mix comprising four major components: a CRISPR enzyme, a guide RNA (gRNA), an aptamer (e.g., an inhibiting aptamer or an activating aptamer) and a “signaling” (i.e., reporter) enzyme. The aptamer interacts with the signaling enzyme and forms a complex, resulting in, e.g., inhibited signaling enzyme activity. When a target is present in the reaction mix, the Cas/guideRNA system becomes activated and preferentially collaterally cleave(s) all nucleic acids in the solution, including the aptamer. Once aptamer gets cleaved, the signaling enzyme is free to produce a signal. In the presence of a substrate, such signaling enzyme activity produces a robust signal that significantly improves the limit-of-detection of other techniques in the art.

  • Publication number: 20250227252
    Abstract: A method for video encoding includes determining an inferable condition for a flag of a specific prediction mode for a current block. The specific prediction mode is one of a plurality of inter picture prediction modes, the inferable condition is based on whether the specific prediction mode and other modes in the plurality of inter prediction modes are allowed, and the other modes are at a lower level than the specific prediction mode in a tree structure. Encoding of the flag in a video bitstream is skipped when the inferable condition indicates that the flag is inferable. The flag is encoded in the video bitstream when the inferable condition indicates uncertainty for inferring the flag. The current block is encoded according to the specific prediction mode when the flag is indicative of an application of the specific prediction mode on the current block.
