  • Publication number: 20220014781
    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: 11222053
    Abstract: An approach is provided for searching multilingual documents. A first classification is determined that includes a first document and other document(s) by minimizing a first distance between a first numerical fixed length vector for the first document and other numerical fixed length vector(s) for other document(s). Based on a query and a natural language detected in the query, a second document is selected. A second stream modeling the second document is encoded as a second numerical fixed length vector. Based on a distance between the first and second numerical fixed length vectors being less than a threshold, the first classification is identified as including the second document. Documents in the first classification are ranked and presented as having content matching the second document's content. At least one of the ranked documents is expressed in a natural language different from the natural language of the second document.
