Abstract
A feature data encoding method is provided. First feature data corresponding to each of channels to be encoded is determined; data type conversion processing is performed on the first feature data corresponding to each channel to obtain second feature data that meets a data input condition of an apparatus for encoding feature data; spatial re-expression is performed on the second feature data corresponding to each channel to obtain third feature data, wherein a height of the third feature data is a first height, a width of the third feature data is a first width, and the third feature data comprises the second feature data located at a target position of each of the channels; and the third feature data is encoded and signalled in a bitstream.
