  • Publication number: 20210120269
    Abstract: A method and apparatus for video coding incorporating enhanced multiple transform (EMT) are disclosed. According to one method, the number of candidates for EMT in the horizontal direction or vertical direction is reduced depending on the current block size. According to another method, an EMT flag, one or more EMT indices or both are signalled only if the total number of non-zero coefficients in at least a part of the 2D coefficient block is greater than a threshold, where the threshold is equal to 1 or larger. A method and apparatus for video coding using non-separable secondary transform (NSST) are disclosed. According to this method, a total number of non-zero first coefficients in a partial block of the 2D coefficient block is determined and used to determine whether to apply the NSST process.

  • Publication number: 20210113182
    Abstract: An ultrasound imaging system which uses multiline receive beamforming for synthetic transmit focusing are phase adjusted to account for speed of sound variation in the transmission medium. The phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the frequency domain for both the transmit angular spectrum and the receive angular spectrum. The phase variation is removed in the frequency domain, then an inverse Fourier transform is used to transform the frequency domain results to the spatial domain. In another implementation, the phase discrepancy of the received multilines is estimated and corrected entirely in the spatial domain.

  • Patent number: 10986365
    Abstract: A method and apparatus provide adaptive interpolation filter for motion compensation with fractional-pixel accuracy. Embodiments of the present invention generate interpolated reference samples at non-integer locations based on existing reference samples in a reference block by using an interpolation filter set adaptively according to pixel location and/or pixel characteristics. A current block is then encoded or decoded using a temporal predictor including the interpolated reference samples. The adaptive interpolation filter can be applied to the prediction unit (PU). In one embodiment, the interpolation filter set consists of interpolation filters having different filter lengths. An interpolation filter with a longer tap length is applied to generate interpolated reference samples farther from the block boundary and an interpolation filter with a shorter tap length is applied to generate interpolated reference samples closer to the block boundary.

  • Patent number: 10979707
    Abstract: A method and apparatus of video coding using adaptive Inter prediction are disclosed. A selected Inter prediction process is determined, wherein the selected Inter prediction process selects an Inter prediction filter from multiple Inter prediction filters for the current block depending on first pixel data comprising neighbouring reconstructed pixels (NRP) of the current block. The selected Inter prediction process may be further determined depending on extra motion compensated pixels (EMCP) around a motion-compensated reference block corresponding to the current block. Distortion between the NRP and EMCP can be used to determine the selected Inter prediction filter. The distortion can be calculated using a sum of absolute differences or squared differences between the NRP and the EMCP.

  • Patent number: 10945660
    Abstract: The present invention relates to monitoring biological tissue during a delivery of energy. A probe-driving unit repeatedly drives an integrated push-and-track transducer unit, which is external to the control device, in repeatedly providing at least one ultrasonic push pulse (302) that is suitable for displacing biological tissue at a monitoring location (M), and in providing ultrasonic track pulses (301, 303) suitable for detecting tissue displacement occurring in response to the push pulse at the monitoring location, and in detecting and delivering ultrasonic tissue-response signals (R) relating to the track pulses. An evaluation unit receives the tissue-response signals, determines in real time whether a normalized displacement quantity has reached a threshold value, and provides an output signal when the threshold value has been reached.

  • Publication number: 20210076061
    Abstract: Exemplary video processing methods and apparatuses for coding a current block by overlapped sub-block motion compensation split the current block into overlapped sub-blocks, determine a sub-block MV for each overlapped sub-block, derive an initial predictor for each sub-block by motion compensation using the sub-block MV, derive a final predictor for each overlapped region by blending the initial predictors of the overlapped region, and encode or decode the current block based on the final predictors. Exemplary video processing methods and apparatuses for coding blocks with OBMC generate a converted MV by changing a MV to an integer MV or changing a MV component to an integer component, derive an OBMC region by motion compensation using the converted MVs, and encode or decode the blocks by blending an OBMC predictor with an original predictor.

  • Publication number: 20210076035
    Abstract: A method for signaling subpicture structures for coded video is provided. A video decoder receives data from a bitstream to be decoded as a sequence of video pictures. The video decoder receives from the bitstream subpicture specification for one or more subpictures in the sequence of video pictures. The subpicture specification identifies a position and a size for each subpicture by providing an index that identifies a coding tree unit (CTU) for the subpicture. The video decoder reconstructs each subpicture for the sequence of video pictures according to the subpicture specification.

  • Patent number: 10944983
    Abstract: A method and apparatus for motion information coding not only uses the Merge index to indicate the selected Merge candidate, but also refines partial motion information of the selected Merge candidate. An encoder derives a Merge candidate set based on the motion information associated with neighboring blocks. The encoder selects a target Merge candidate from the Merge candidate set and signal a Merge index corresponding to the target Merge candidate. The encoder then predicts a part of the current motion information based on partial motion information associated with the target Merge candidate to generate coded motion information.

  • Patent number: 10944989
    Abstract: A method and apparatus for Intra prediction of non-square chroma blocks are disclosed. The system uses a block partitioning structure for partitioning a chroma block into one or more final sub-blocks including at least one non-square final sub-block using block partition recursively. The block partition either splits each given block into intermediate sub-blocks using one or more split modes including one binary split mode or applies no splitting to each given block. The block is treated as an initial given block and each intermediate sub-block is treated as one given block in a next recursion. Any given block that is not further split becomes a final sub-block. After the final sub-blocks are determined, non-square Intra prediction is applied to each non-square final sub-block.
