    Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method may comprise obtaining, from a bitstream, a feature set extracted from an input image using an artificial neural network-based feature extraction method, first information on importance of each of a plurality of channels included in the feature set and second information on a quantization method of the feature set, decoding the feature set, the first information and the second information, and dequantizing the decoded feature set based on the decoded first information and the decoded second information. The second information may comprise the number of quantization bits of each of the plurality of channels, and the number of quantization bits may be determined based on the importance of each of the plurality of channels.

    Abstract: An intra prediction method according to the present invention comprises the steps of: acquiring information on a luma prediction mode of a current block and information on a chroma prediction mode of the current block from a bit stream; deriving a luma intra prediction mode of the current block on the basis of the information on the luma prediction mode; determining a chroma intra prediction mode of the current block on the basis of information on the luma intra prediction mode and the information on the chroma prediction mode; and generating a chroma prediction sample of the current block on the basis of the chroma intra prediction mode. According to the present invention, it is possible to reflect the difference between the ratio of the width to the height of a luma component and the ratio of the width to the height of a chroma component, and thus to more accurately perform intra prediction in units of samples and improve intra prediction performance.
