Abstract: Provided are a feature encoding/decoding method and device, a recording medium on which a bitstream generated by the feature encoding method is stored, and a method for transmitting the bitstream. The feature decoding method according to the present disclosure comprises the steps of obtaining vertical channel information related to vertical-direction channels and horizontal channel information related to horizontal-direction channels in a feature map; identifying channel boundaries in the feature map on the basis of the vertical channel information and the horizontal channel information; and decoding the feature map on the basis of the channel boundaries, wherein the vertical channel information includes either first information related to the boundaries of the vertical-direction channels or second information related to the number of vertical-direction channels, and the horizontal channel information can include either third information related to the boundaries of the horizontal-direction channels or fourth information related to the number of horizontal-direction channels.
