  • Patent number: 12028512
    Abstract: The present disclosure provides a method for inter-frame prediction of a coding unit in an image. The method may include obtaining a first MV candidate list corresponding to the coding unit and the first MV candidate list may be constructed based on a non-triangle prediction mode, such as a merge mode. The method may also include determining, based on the first MV candidate list, a second MV candidate list corresponding to the coding unit. The second MV candidate list may be a triangle candidate list used for inter-prediction using a triangle prediction mode. MVs in the second MV candidate list may be determined based on MVs in the first MV candidate list. The method may also include determining, based on the second MV candidate list, a target prediction unit of the current coding unit according to a triangle prediction mode.

  • Patent number: 11948031
    Abstract: A method for authenticating a passive RFID tag includes acquiring a tag fingerprint of a first tag as a first tag fingerprint, the first tag being the genuine tag; acquiring a tag fingerprint of a second tag as a second tag fingerprint, the second tag being the tag to be authenticated; comparing the first tag fingerprint with the second tag fingerprint: if the first tag fingerprint is consistent with the second tag fingerprint, determining that the second tag is a genuine tag, otherwise determining the second tag is a forged tag. The tag fingerprint is the persistence time enabling the passive RFID tag to operate normally during discharge after fully charging. The beneficial effects include being high in robustness to the change of environment and high in authentication accuracy and capable of being directly deployed on an existing commercial RFID device without modifying hardware of the tag and reader.
