Abstract: A feature map encoding method according to the present disclosure may include generating a feature map from a multi-level feature group; and performing PCA (Picture Component Analysis) transform for the feature map. Here, generating the feature map comprises reshaping the multi-level feature group; and generating the feature map by merging a plurality of base units generated by the reshape.

Abstract: A device for decoding a feature map according to the present disclosure comprises an image decoding unit to decode an image from a bitstream; an inverse format conversion unit to restore a feature map latent representation by converting a formation of a decoded image; and a feature map restoration unit to restore a multi-layer feature map from the feature map latent representation. Here, the feature map restoration unit restores the multi-layer feature map based on a learned neural network parameter.

Abstract: A feature map decoding method according to the present disclosure may include decoding a metadata and the feature map; performing inverse conversion on a decoded feature map; and restoring features from inverse converted features. Here, a feature distortion compensation is performed on at least one of the decoded feature map, the inverse converted features or restored features.

Abstract: The present disclosure provides a method and a device for encoding/decoding a multi-scale feature group. A multi-scale feature group encoding method according to the present disclosure includes transforming a multi-scale feature group into a multi-channel feature; adjusting the number of channels of the multi-channel feature; acquiring a plane image based on a feature that the number of channels is adjusted; and encoding the plane image.
