  • METHOD FOR ENCODING AND DECODING RESIDUAL SIGNAL BASED ON PERIODICITY OF PHASE SIGNAL AND APPARATUS THEREOF
    Publication number: 20230230284
    Abstract: The residual signal encoding and decoding method and apparatus based on a periodicity on phase signal are disclosed. One embodiment on a method for decoding an image, the method comprising: generating a prediction signal for a current signal, decoding an encoded residual signal from a bitstream, generating an initial reconstructed signal based on the prediction signal and the residual signal, and generating a transformed reconstructed signal by transforming a value of the initial reconstructed signal to have a size value of a preset range, wherein the generating of the transformed reconstructed signal generates the transformed reconstructed signal from the value of the initial reconstructed signal by using a clipping function with a minimum value of the preset range and a maximum value of the preset range as input values, and wherein the preset range is a period range of a signal.
