Abstract
An encoding method, a decoding method, an encoder, a decoder, and a storage medium are provided. The encoding method comprises: determining input feature map data (S201); performing relevant processing on the input feature map data to obtain a plurality of feature sub-maps (S202); reordering the plurality of feature sub-maps to obtain a quasi time domain sequence and corresponding reordering information (S203); and encoding the quasi time domain sequence and the reordering information to generate a bitstream (204).
