  • Publication number: 20240107002
    Abstract: A method for coding image information includes generating prediction information by predicting information on a current coding unit, and determining whether the information on the current coding unit is the same as the prediction information. When the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted. When the information on the current coding unit is not the same as the prediction information, a flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted.

  • Publication number: 20240073416
    Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

  • Patent number: 9415813
    Abstract: A foldable vehicle may include a front floor coupled with front wheels and a rear floor coupled with rear wheels, wherein the front floor and the rear floor increase or decrease a wheelbase of the vehicle by sliding over and under each other, a windshield part hinged to the front floor to turn forward or backward, a rear cabin part hinged to the floor part to turn forward or backward, and a roof part hinged to an upper end of the windshield part and hinged to an upper end of the rear cabin part, wherein the roof part may be configured to be stowed inside the vehicle when the windshield part and the rear cabin part may be folded inward, and may be configured to be exposed to the outside to form a roof of the vehicle when the windshield part and the rear cabin part may be unfolded outward.

  • Patent number: 9199671
    Abstract: A folding unit for a foldable vehicle comprises a floor part configured including a front floor provided with a front wheel and a rear floor provided with a rear wheel. The front floor and the rear floor overlap each other or extend by being slid to each other to extend or contract a wheelbase of the vehicle. A rear cabin part is disposed at a rear side of the vehicle to form a dome shaped cabin and has a lower end hinge-coupled with the floor part to rotate in a front and rear direction of the vehicle. A folding driver includes a linear motor rotating while being hinge-coupled with the floor part. An operating rod is extended or contracted from the linear motor and has an end hinge-coupled with a lower end of the rear cabin part.
