  • Patent number: 10743029
    Abstract: Aspects of the disclosure provide method and apparatus for video coding. In some embodiments, an apparatus includes a processing circuitry. The processing circuitry decodes partition information of a block associated with a picture in a coded video bitstream. The partition information is indicative of a coding tree structure. Then the processing circuitry partitions the block into one or more coding blocks according to the coding tree structure. After the block is partitioned into multiple coding blocks, the processing circuitry groups the one or more coding blocks into non-overlapping grouped coding blocks such that each of the non-overlapping grouped coding blocks includes at least one coding block. Finally, the processing circuitry reconstructs the block based on the non-overlapping grouped coding blocks.

  • Patent number: 10742972
    Abstract: A method of video decoding in a decoder is described. A first syntax element in a coded video bit stream is received. The first syntax element indicates a maximum allowed number of merge candidates in a set of coding blocks. A maximum allowed number of triangular prediction mode (TPM) candidates for the set of coding blocks is set based on a second syntax element when the second syntax element is received, otherwise it is set based on the first syntax element. When a current coding block in the set of coding blocks is coded in a triangular prediction mode, a triangular prediction candidate list of the current coding block is constructed based on a number of TPM candidates. The number of TPM candidates on the triangular prediction candidate list is equal to the maximum allowed number of TPM candidates.

  • Patent number: 10742975
    Abstract: A video coding device receives a bitstream including video data. The device determines an intra-prediction mode subset. The intra-prediction mode subset include intra-prediction modes that correlate to a plurality of reference lines for a current image block and excludes intra-prediction modes that correlate to a primary reference line for the current image block. When a first intra-prediction mode is included in the intra-prediction mode subset, the device decodes the first intra-prediction mode by an alternative intra-prediction mode index. When the first intra-prediction mode is not included in the intra-prediction mode subset, the device decodes the first intra-prediction mode by an intra-prediction mode index. The device presents video data including an image block decoded based on the first intra-prediction mode.

  • Patent number: 10735759
    Abstract: 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 prediction mode that uses a motion vector predictor candidate list for reconstructing the current block. The processing circuitry includes a new motion vector predictor into the motion vector predictor candidate list. The new motion vector predictor is one of a first motion vector predictor and a second motion vector predictor. The first motion vector predictor is a first average result of a pair of existing motion vector predictors in the motion vector predictor candidate list and a temporal motion vector predictor (TMVP). The second motion vector predictor is a second average result of a pair of history-based motion vector predictors (HMVPs) in an HMVP buffer. The processing circuitry reconstructs the current block based on the motion vector predictor candidate list.

  • Patent number: 10734070
    Abstract: Non-volatile memory strings may include multiple selection devices for coupling memory cell devices to a bit line. Different programming operations may be used to program various individual selection devices in a non-volatile memory cells string. For example, a control circuit may set a threshold voltage of a particular selection device to a value greater than a threshold voltage of another selection device. In another example, the control circuit may program the selection device using an initial sense time. Subsequent to programming the selection device using the initial sense time, the control circuit may program the selection device using a different sense time that is shorter than the initial sense time.

    Abstract: Provided is a generation method for a programmable analog fringe pattern with an extended depth of field. A laser emits a laser beam. After focusing and collimation thereof with a collimating lens, a collimated Gaussian laser beam meeting requirements is obtained. The laser beam is reflected by a mirror once, passes through a round diaphragm and is incident on a MEMS scanning mirror. The beam is reflected by the MEMS scanning mirror to the surface of a tested object. The laser is controlled by a sinusoidal current signal generated by a drive board so as to sinusoidally modulate the brightness of the laser beam. The MEMS scanning mirror is stimulated by a drive signal generated by the drive board to turn two-dimensionally, so as to drive the laser beam to perform scanning, thus generating a fringe pattern image.
