The present invention relates to an entropy encoding method, an entropy decoding method and to an apparatus using same. The entropy decoding method includes: a step of decoding a bin of a syntax element; and a step of acquiring information on the syntax element based on the decoded bin. In the step of decoding the bin, context-based decoding or bypass decoding is performed for each bin of the syntax element.

Entropy decoding method, and decoding apparatus using same

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.

Image encoding/decoding method and device for performing feature quantization/ de-quantization, and recording medium for storing bitstream

An image encoding/decoding method and apparatus are provided. An image decoding method comprises obtaining, from a bitstream, encoded data of feature information generated by applying an artificial neural network-based feature extraction method to an image, reconstructing feature information by decoding the encoded data of the feature information, and generating analysis data of the image based on the feature information.

Image encoding/decoding method and apparatus for signaling image feature information, and method for transmitting bitstream
