摘要： This application discloses encoding and decoding methods and apparatuses, and relates to the field of artificial intelligence technologies, to improve rate distortion performance of data encoding and decoding methods. The method includes: first obtaining to-be-encoded data, and then inputting the to-be-encoded data into a first encoding network to obtain a target parameter; then constructing a second encoding network based on the target parameter; next inputting the to-be-encoded data into the second encoding network to obtain a first feature; and finally encoding the first feature to obtain an encoded bitstream.

摘要： A video frame compression method includes determining a target neural network from a plurality of neural networks according to a network selection policy; and generating, by using the target neural network, compression information corresponding to a current video frame. If the compression information is obtained by using a first neural network, the compression information includes first compression information of a first feature of the current video frame, and a reference frame of the current video frame is used for a compression process of the first feature of the current video frame. If the compression information is obtained by using a second neural network, the compression information includes second compression information of a second feature of the current video frame, and a reference frame of the current video frame is used for a generation process of the second feature of the current video frame.
